Ranking the 10 Best Basketball Leagues in Europe: Turkey Sits Second — And My Spreadsheet Says That Seat Is Shaking

On 8 July 2026, the Hellenic Basketball Federation published the details of its new television deal: 21 million euros spread across three seasons, with each of the league's 14 clubs receiving a minimum of 700,000 euros per season directly from the league office. The number did not shock anyone. It quietly buried an assumption European media had hugged for a decade — that domestic leagues are the undercard, and the real money lives in the EuroLeague and EuroCup.

I reopened a four-year-old spreadsheet of mine — the file tracking the 47 events that led to Cristiano Ronaldo leaving Manchester United — and added a new sheet. Header: Europe 2026. Three columns: television revenue, average revenue per club, and governance quality. Not one column measuring points per game.

That is where everything starts. A spreadsheet does not lie — only the person too lazy to read it fools himself.

Context: a race on a track nobody has drawn yet

For years, the question of which European domestic basketball league is strongest was answered by instinct. Spaniards pointed to Liga ACB. Turks pointed to their three EuroLeague teams. Greeks banged the table when Olympiakos won Europe. Nobody had a shared yardstick, because no organisation had stepped up to measure.

That is about to change.

In 2027, the NBA is expected to launch NBA Europe — an NBA-operated competition aimed at the European market. The mechanism has not been fully published, but one detail has leaked and is enough to keep every league board in Europe awake: FIBA will publish its own ranking of European domestic leagues, and that ranking will play a role in selecting teams for an end-of-season tournament competing for two places in the new NBA Europe league.

Read that again. A ranking drawn up by FIBA, used to allocate places in a league run by the NBA.

I am not writing about transfer rumours here. I am writing about structure. And the structure of European basketball has just gained a new floor: the ranking floor.

Against that backdrop, a ranking of the ten strongest leagues in Europe has appeared, built not on points per game or point differential, but on four pillars: financial strength, governance capacity, market size, and the quality of the on-court product — in that order of priority. The results irritate a lot of people. And as always, uncomfortable numbers tend to be the correct ones.

Core: dissecting each league like a case file

Spain — a first place with no challenger

Liga ACB remains first. There is no argument here, and no surprise either. What matters is how that position is described: Spain has advantages at every level compared to all other domestic or regional leagues. Not an advantage in one category. An advantage in every category.

Liga ACB operates as a closed, controlled ecosystem: a youth development system that produces players at the highest success rate in Europe, clubs with a relatively disciplined financial culture, and a league capable of turning the domestic arena into a quality checkpoint before players step into the EuroLeague.

But there is a crack my spreadsheet records clearly. Spain is monetising itself below its potential. Its financial advantage is described as theoretical rather than realised. The league should be generating much more revenue for its clubs, at least theoretically, than the money currently being discussed for continental competitions in Europe.

Translated from spreadsheet into human: Spain has the best product but sells it below its true value. That is the kind of mistake a good administrator does not make three years running. It is also why I am not betting on Spain losing its crown in the short term — the gap is too wide to be erased by one bad season — but it is why I am watching for who in Europe will be first to sign a domestic television deal worth more than 100 million euros per season. When that happens, it will happen in Spain or Greece. Nowhere else.

Turkey — a second place standing on sinking ground

Basketbol Süper Ligi is second. On paper, the position is deserved: three EuroLeague teams, a run of domestic finals with high technical quality, and a market of nearly 85 million people.

This is where I need to be blunt. Turkey's second place is not a statement about the strength of Turkish basketball. It is a statement about historical inertia, sustained by three clubs with European budgets, resting on an economy in difficulty and a league office that has produced no significant new revenue stream.

The precise phrasing used in this ranking: the Turkish BSL could lose its second place in the ranking if dynamics do not change next season. And in another line: league management needs to be more proactive in generating revenue.

Two sentences, placed side by side, form a clinical diagnosis. The league is strong operationally but weak in profitability. In the European basketball model, a league can survive without major television revenue, as long as clubs fund themselves. But it cannot hold its ranking position when the ranking criteria are shifting towards league-level financial indicators.

I have tracked this kind of shift before. In 2026, when Wigan Athletic went bankrupt and were docked 12 points, I wrote a prediction on my blog about the release clause in Kieffer Moore's contract. On 9 September 2026, Cardiff City confirmed the signing. Wigan's bankruptcy was not a shock — it was a forecast line written three years earlier.

What I learned from that case, and from four years tracking European clubs: an organisation does not collapse because of one bad season. It collapses because three consecutive years pass with an unchanged revenue structure while operating costs rise. BSL is not there yet. But if I had to set a marker, I would say this: if by the end of the 2027-28 season BSL has not signed a significantly more valuable new domestic television deal, second place belongs to Greece.

Greece — the third-placed league raising its hand

The Greek Basketball League is third. But read one line carefully: it is almost at the same level as the BSL.

The 21-million-euro television deal over three seasons is a figure many will underestimate because it looks small against NBA standards. Put it next to another number: each club receives a minimum of 700,000 euros per season directly from the league. That figure is much larger than the average revenue the EuroCup and the BCL bring to their participants.

Read that again. Playing in the Greek domestic league now pays better than playing in a continental competition.

This is an inflection point European media has not yet processed conceptually. For two decades, the logic of European basketball was: domestic leagues are the vehicle, continental competition is the destination. Players chose clubs because they wanted EuroLeague basketball. Clubs spent money because they wanted continental places. Money flowed downhill.

Greece has just partially reversed that flow. By centralising television rights and redistributing them through a mechanism that guarantees a floor for every club, they turned domestic revenue from a variable into a constant. For a mid-sized club, a fixed 700,000 euros per season is worth more than a variable sum with a higher expected value but also a higher standard deviation. That is mathematics, not sentiment.

And Greece has something no other European league has right now: a domestic EuroLeague champion, alongside EuroLeague ambitions from clubs outside the Olympiakos–Panathinaikos duopoly. The power structure of Greek basketball is expanding from a bipolar to a multipolar shape.

I keep a separate column in my spreadsheet for Greece, marked: governance quality — strongest in the group. That is an assessment I do not hand out lightly. In European basketball, league offices are often where administrative careers come to retire. Greece is doing the opposite.

The only risk, and it is large: off-court incidents. These remain a big and almost unsolvable problem, despite some improvement compared to the 2026-25 finals. A league with rising revenue but damaged reputation trades growth rate for stability. With a ranking drawn up by FIBA — an organisation with a history of intervening in national federations — reputation is no longer a media matter. It is a scoring matter.

Italy — the returnee coming from behind

After many ups and downs, Italy appears to have returned.

That sentence, standing alone, sounds like a platitude. Placed next to two other facts, it becomes an argument: one, two team projects involving Luka Doncic and Francesco Totti moving to Rome; two, the presence of Maurizio Gherardini — a long-time sports executive — as league president.

I want to separate these two facts, because they belong to different categories and many readers merge them.

The second fact is the durable kind. A league president with senior executive experience affects structure: scheduling, television relations, FIBA relations, club licensing standards. This kind of impact creates no headlines but creates stable cash flow over three to five years.

The first fact is the volatile kind. Bringing a Doncic-linked team to Rome is a market move built on one individual's commercial pull. This model is new in Europe: using star power and market size to compensate for traditional basketball infrastructure. If it works, other leagues will copy it. If it fails, it becomes a lesson in building a house from the roof down.

In my spreadsheet, Italy sits in the group with the highest probability of climbing within two to three seasons. But I attach a warning: that climb depends on whether money from the Rome projects converts into sustainable revenue or merely short-term attention. Attention does not pay player salaries.

France — the most talent and the least money

This is the hardest section to write, and I will write it in two short sentences.

France has the best raw talent in Europe. France has fallen two places compared to two years ago because its most recent champion — Monaco — was relegated to the third division due to financial difficulties.

I have spent three seasons tracking the French league, and what bothers me is not the ranking. It is the structure.

France is Europe's leading producer of basketball talent, and this makes their on-court product — purely in terms of athletic talent — unmatched in balance and raw talent by any other league in Europe. But that very advantage becomes a curse. France is blessed with Victor Wembanyama, and this is also a curse for the local league, because for most fans basketball is still synonymous with the NBA.

Stop on that sentence, because it is one of the sharpest observations in the entire dataset I am analysing.

The structural problem of French basketball is not a shortage of players. The problem is that fan attention flows straight from the domestic league to the NBA without stopping anywhere. When a young French talent appears, the first question is not which Betclic Élite team he will play for, but which NBA draft slot he will land in.

The result is a system that produces talent but cannot retain talent value. And that shows up in the spreadsheet: weak revenue, weak governance, and a top-level financial shock — the relegation of the reigning champion — that is not a symptom of one bad season but a symptom of a model.

Numbers do not interrupt the story — they tell a different one, and they are rarely wrong.

Tony Parker starting his head coaching career will attract the attention of the entire basketball world. That is a good fact for French media. It is not a good fact for the league's balance sheet. I separate those two things, and I advise anyone reading sports news to separate them too.

Adriatic — expansion that looks beautiful on paper

The league covering the former Yugoslavia countries recently expanded to include Dubai BC, who won the championship last season. Alongside them: teams from Romania, Slovakia and Austria.

Read that list and you see clear ambition: increase market footprint, increase competitive depth, and — more importantly — increase weight in a ranking FIBA is about to publish.

But my spreadsheet has another column, and that column reads: complex structure, especially financially.

This is a sign I see in many leagues trying to accelerate: adding revenue without solving the core governance problem. More teams means more markets, but also more variables in an equation that was already hard to solve. If Dubai BC wins, questions about the interests of founding clubs will surface. If one of the expansion teams hits financial trouble, pressure falls on the whole system.

And the biggest problem for the Adriatic is not the ranking. It is the talent flow. Local talents are lost at a very early age and go almost anywhere in the world due to financial incentives, and that lowers the value of the Adriatic league.

A league losing young talent early is a league selling its future to pay for its present. The appointment of Ibrahim Erkan — nominated for the new Sporting Director role, expected to leave the EuroLeague and his similar post there to move to the Adriatic league — is a positive signal of administrative professionalisation. But a good sporting director cannot compensate for an uncontrolled outflow of cash.

Germany — stability, and that is exactly the problem

The Basketball Bundesliga has talented players and a world-champion national team. On paper, that is the foundation of a top league.

But my spreadsheet records two words: stable but stagnant.

The difference between stability and stagnation, in league analysis, comes down to one question: has the league's revenue structure changed in the past three years? If yes, that is stability. If no, that is stagnation. For the BBL, the answer is no. Weak revenue and local-only interest — that is an accurate description of the German league's current state.

This is the paradox of European basketball I keep meeting in different countries: national team success does not automatically translate into domestic league strength. Germany won the world title, but that did not raise the price of Bundesliga broadcast rights.

I keep Germany in the middle group, with a note: if the BBL does not change its revenue model within two seasons, it will lose its place to a league that is accelerating. And the clearest candidate for that place is Italy.

Lithuania — one team, one league

This is the shortest line in my spreadsheet, and I keep it short because the brevity is the message.

Lithuania has Zalgiris. In terms of basketball quality, Zalgiris is a European-calibre organisation. But a league whose competitive structure is dominated by one club is not a top-tier league — it is a club with its own league.

In a ranking based on market size and revenue generation capacity, Lithuania hits a physical population ceiling. That is not their fault. But it is a reality a ranking must reflect if it wants predictive value.

Israel — constrained by a variable off the court

The Israeli league is affected by the geopolitical situation. I will not analyse that factor in depth, because it is not a basketball question. But I record something sports analysis often ignores: geopolitical risks affect scheduling, the ability to attract foreign players, and the value of international broadcast rights. They are a variable in the spreadsheet, not a footnote in the margin.

United Kingdom — the biggest media market, the weakest product

The United Kingdom is the largest media market where the domestic league operates following FIBA intervention in the national federation. And the UK remains far from serious consideration for a top-10 place.

This is the single most important fact in this entire section, and it breaks a popular assumption.

That assumption is: market size determines league quality. The UK has roughly 68 million people, one of the world's largest media industries, and an extraordinarily developed sports culture. If market size were the deciding factor, British basketball would be among Europe's leaders. It is not.

My spreadsheet records the cause structurally: market size is a necessary condition, not a sufficient one. What turns a necessary condition into an outcome is governance quality and the presence of a competitive product. The UK has the former and lacks the latter, and FIBA's intervention in the national federation is evidence that the problem sits at the governance level, not at the demand level.

I have tracked British basketball since 2026, when I began writing an NBA column for a Vietnamese outlet. In those seven years, I have not once seen a data line suggesting British basketball is closing the gap on the top ten. This is the kind of observation data does not allow you to hope about. It only allows you to record.

The counterintuitive angle: this ranking does not measure basketball

This is the part I want to state most clearly, because it runs against most readers' instinct.

A ranking of the ten strongest basketball leagues in Europe, read carefully, says almost nothing about basketball.

It does not discuss offensive or defensive efficiency. It does not discuss pace. It does not discuss tactical systems, how teams use the pick-and-roll, whether wings invert or hold the sideline. Across the entire dataset I analysed, there is exactly one reference touching the on-court product: the claim that France has the best balance and raw talent in Europe.

One reference. In a document ranking the entire European basketball system.

I read that as a deliberate statement. The hierarchy of European basketball leagues is determined by off-court factors — finances, governance, market size — rather than by playing style or tactical innovation. This aligns with a broader trend: competition in the EuroLeague is driven by budget disparities rather than schematic advantages.

And this is where I have to check myself.

I have a professional bias I recognised long ago: I believe heat maps and advanced metrics have become a new form of fortune-telling, obscuring a player's real role within a tactical system. I also believe the trend of wings inverting is homogenising basketball, and traditional wing players are being wrongly erased.

But in the league-ranking problem, neither of those beliefs helps. The best wing in Europe does not raise his league's broadcast rights value. A sophisticated tactical system does not generate a fixed 700,000 euros per season per club.

Here is what I want readers to take away: when a ranking talks about leagues, it is talking about organisations. When it talks about teams, it is talking about systems. When it talks about players, it is talking about people. Mixing those three layers is the most common error in sports analysis.

And there is one more blind spot I want to raise, because it matters more than all the others.

This ranking is being built against the backdrop of the imminent NBA Europe 2027 launch. FIBA will publish its own ranking, and that ranking will determine the chance to play in an end-of-season tournament for two NBA Europe places. Which means: European leagues are competing for position in a ranking whose criteria have not been fully published, in order to qualify for a competition whose revenue-sharing mechanism has also not been fully published.

In other words, a race is underway on a track nobody has drawn.

There is a structural risk here I want to record clearly in the spreadsheet: FIBA is the body drawing up the ranking and also the body with a relationship to NBA Europe in determining access. Leagues with better FIBA relations may benefit from more favourable ranking criteria. I put the probability of this scenario at low, but I record it, because a non-transparent assessment system is a system that can be gamed.

And there is one impact I consider near certain.

NBA Europe 2027 may create a Matthew Effect in European basketball: leagues already strong — Spain, Turkey, Greece — will gain disproportionate access to new revenue, while weaker leagues — France, the Adriatic, Germany — fall further behind. The result could be a consolidation of European basketball around three or four dominant leagues.

I am not writing this as a pessimistic forecast. I am writing it as a forecast with an expiry date.

Over the next 24 months, I predict: Greece will overtake Turkey in the FIBA ranking. Probability: 60 per cent.

If I am wrong, I will reopen this sheet and record exactly where I was wrong. That is how I protect credibility — not by being right, but by letting readers see the wrong parts too.

The next dominoes

There are six signals I will track next season, and I list them here so anyone can verify me later.

One, implementation of the Greek television deal. I track per-club revenue distribution and competitive balance. If clubs receive 700,000 euros or more and reinvest in roster quality, the Greek league consolidates second or third place. Trigger condition: a mid-sized Greek club signs a EuroLeague-calibre player previously out of reach.

Two, BSL revenue-generation initiatives. I track announcements from Turkish league management. Trigger condition: a new television deal, a major sponsorship, or a commercial partnership. Expected impact: BSL holds or loses second place.

Three, development of the Rome projects. I track performance and attendance in Rome. Trigger condition: those teams become competitive in the Italian league and European cups. Expected impact: Italy climbs the ranking.

Four, NBA Europe 2027 qualification criteria. I track FIBA announcements. Trigger condition: criteria published and teams begin qualifying. Expected impact: the European league hierarchy reshuffles.

Five, financial sustainability of the Adriatic league. I track the financial reports of new teams. Trigger condition: Dubai, Cluj-Napoca, Slovan and Vienna remain solvent. Expected impact: the Adriatic expansion succeeds or fails.

Six, French financial reform. I track governance changes in the league. Trigger condition: new financial rules or licensing requirements. Expected impact: France's ranking stabilises or keeps falling.

I do not offer these six signals because I enjoy making lists. I offer them because a forecast without verification points is an opinion, and opinions do not need spreadsheets.

What I actually think

There is a line I wrote in the spreadsheet tracking 30 transfers from summer 2026, when I was seventeen and a Chelsea fan account asked what a girl knows about transfers. I did not answer with emotion. I posted a spreadsheet.

Thirty transfers in one summer, every line a promise — I still keep them to check against.

Eight years later, I am doing the same thing, only at a larger scale. The ranking of the ten best basketball leagues in Europe I analysed above is not a verdict. It is a record.

What I actually think, after reading all the data, is this: European basketball is going through a restructuring that most fans will not notice until it is complete. That restructuring is not driven by players, by coaches, or by tactics. It is driven by television deals, revenue-distribution mechanisms, and a ranking that has not yet been published.

Turkey's second place is the anchor of the old order. Greece's rise is the signal of the new one. France's financial collapse is proof that talent protects nobody from a balance sheet. And the stagnation of Germany, Lithuania, Israel and the UK is proof that market size and history are no longer enough to hold a position.

I have tracked enough club bankruptcies to know one thing: no organisation collapses because of a single wrong decision. They collapse because a wrong structure is repeated often enough.

And the question I leave for next season is not which team will win the EuroLeague. The question is: when FIBA publishes its ranking, how many league boards in Europe will discover they spent years optimising the wrong thing?

Data is never innocent, only its owner is.
