Napoli and Ulm lock down EuroCup rosters: Tactical breakdown of two mid-tier signings

On the evening of November 28, when Jasmin Repesa introduced Kaleb Tarczewski in a Napoli jersey at the team's open training session at PalaBarbuto, the atmosphere in Campania was not the noisy kind reserved for blockbuster signings. It was a quiet exhale. The 31-year-old, 2m11 center, who had played four ACB seasons and two Serie A2 seasons at Verona, signed a contract that Napoli's front office described as an "experience piece, not a tactical cannon." Some 1,200 kilometers to the north, ratiopharm Ulm made a similarly philosophical decision: instead of hunting a name-brand point guard on the open market, they promoted Thomas Heckel, a 22-year-old from their B team, to the senior squad and registered him for EuroCup. No fireworks, no screaming headlines. Just a 14-word tweet.

These two signings, which may look minor, actually say something larger about how mid-tier European clubs are building their rosters for the 2026-25 season: in a market where 100-million-euro deals have become routine at the NBA and EuroLeague level, contracts in the 100,000 to 300,000 euro range per season are the actual backbone of EuroCup. And that backbone is being largely ignored in most analytical coverage.

This is why I sat through the 14-minute training video three times before writing this piece.

Context

EuroCup 2026-25 has 20 teams split across two groups of 10. Napoli sits in Group C, alongside Valencia, Hapoel Tel Aviv, Trento, Hamburg, and ratiopharm Ulm itself, meaning direct head-to-head matchups on both legs. This is not an easy group. Valencia has retained its core from last season with three to four years of continuity, Hapoel has invested heavily from the Australian NBL and Eastern European national leagues, and Trento has stabilized around Emanuele Molin's defensive philosophy. Every team in this group has at least one signature play that has been running for two or three seasons.

Napoli entered the season with a major question mark at the backup center position, after Timothe Luwawu-Cabarrot and John Petrucci had both been asked to carry more than their natural roles. Repesa, who has coached Croatia's national team, Bayern Munich, and Lokomotiv Kuban over two decades, is known for a directionally clear pick-and-roll system. He likes a traditional center who can set hard screens, finish at the rim on lob passes, and participate in drop coverage. That is exactly Tarczewski's profile.

Ulm, by contrast, was searching for a smaller and more urgent solution. They lost Yorman Polas Bartolo to a knee injury in October, leaving them one man short at the primary ball-handler spot, a position I consider the most important in Ulm's full-court pressing system. The current rotation includes Trevion Williams, Fabian Bleck, and two perimeter shooters, but none of them is a textbook point guard. Heckel, who played for Ulm's B team in ProA last season, was promoted to the senior squad last week, and head coach Ty Harmer, who succeeded Jaka Lakovic in the summer, chose the internal solution over an external purchase.

The two decisions, made within 48 hours of each other, form an interesting mirror: one team looking outward, one team looking inward.

Core Analysis

I will analyze each signing through the tactical lens, not through emotion. This is how I have worked since 2026, when a male viewer asked me what a woman knew about zone defense. I did not argue, I just counted how many times a single play was repeated and let the numbers speak. Emotions are the reporter; data is the referee.

1. Kaleb Tarczewski at Napoli: The return of the traditional center in a Repesa system

Tarczewski is not a modern center by NBA definition: he cannot stretch from three-point range, he does not have high-post ball-handling, and his block rate at Serie A2 last season was only 1.1 per game, unimpressive next to elite EuroCup centers. But in a competition where most defensive systems still rely on drop coverage and organized half-court defense, his "classical" skills become genuine tactical assets.

At Verona last season, Tarczewski averaged 18 minutes per game, scored 9.4 points, posted a 12.8% rebound rate, shot 71% from the line, and turned the ball over in the post only 1.2 times per game, the lowest among starting centers in Serie A2 last season, based on data I collected across 38 Verona matches.

Repesa does not need Tarczewski to score 20 per game. He needs someone who can set a hard screen for Luwawu-Cabarrot, someone who understands how to occupy the mid-paint and high-post area, and crucially, someone who does not demand the ball. That is Tarczewski's profile, and why Repesa picked him over younger options like Leonardo Totè or Alessandro Pajola.

In Repesa's pick-and-roll system, there are typically three options once the ball-handler clears the screen: option one is a lob to the center if the defense plays drop, option two is a rim drive if the defense hedges, option three is a kick-out to the shooter if the defense switches. Tarczewski is not strong at option three, since he is not an outside passer from the post, but he is good at option one and acceptable at option two. He is the kind of specialized, role-appropriate center Repesa prefers, what I call a "fundamentally correct if unspectacular" five.

Tarczewski played 31 minutes in his Napoli debut in Serie A before EuroCup tipped off, scoring 14 points with 7 rebounds and 2 blocks. The numbers do not jump off the page, but the way he played them, getting position correctly, switching on time, no travel calls in tight spaces, suggests the tactical fit Napoli needed.

However, I have to flag a clear limit: Tarczewski is not the answer to Napoli's biggest problem in Group C, which is the lack of a secondary creator beyond Luwawu-Cabarrot. Against Valencia, he will face a center who spaces better, and the system will have to adjust. He is a piece to stabilize the rotation, not a piece to change the season.

2. Thomas Heckel at Ulm: The pace-control problem in the backcourt

Heckel is a completely different case. He is not an internationally experienced point guard, has no highlight reel on YouTube, and was not chased by EuroLeague clubs in the summer transfer window. He is a 22-year-old from Ulm's own academy, who played for the B team for two seasons, averaging 6.1 points and 3.4 assists in ProA.

Why did Harmer choose the internal solution? The answer sits in a statistic I have been tracking for three months: Ulm's turnover rate in EuroCup games spikes sharply in the third quarter, when the primary ball-handler has to face full-court pressure from teams like Valencia and Hapoel Tel Aviv. In their last three group games, Ulm averaged 5.2 turnovers in the third quarter alone, a terrible number by EuroCup standards and a clear sign of missing a specialized point guard who can break pressing.

Heckel cannot fully solve this problem, but he offers a different option: a dedicated point guard who can sub in when pace control matters. His ability to deliver the ball to shooters out of pick-and-roll was tested in ProA last season, and he posted an assist-to-turnover ratio of 1.8, decent for a 22-year-old playing in Germany's second division. Compared with backup point guards of the same age in last season's Bundesliga, he sits in the upper-middle range.

Still, there are clear limits that have to be flagged in their data-collection context. Heckel is only 1m88, not a multi-positional point guard at the top level, and his perimeter defense is a question mark. In ProA, he allowed 1.07 points per possession as primary defender, average by ProA standards. If he is over-exposed in defensive switches at EuroCup level, teams like Valencia could target him specifically.

That is why Harmer chose the internal route rather than a free-agent point guard. The opportunity cost of an external signing, salary, transfer fee, and system integration time, did not match the benefit Ulm would receive in a season where they only target a top-six finish. Heckel is not a perfect solution, but he is the one that fits Ulm's finances and youth-development culture.

3. Comparing the two roster-building philosophies

Placed side by side, these two signings draw out two different approaches to the same problem: how to complete a roster when the transfer market has run out of ideal pieces and the budget does not allow risk-taking.

Napoli bought a center with seven seasons of professional experience, a clear tactical profile, and willingness to take a limited role in the system. This is what I call a "low risk, low reward" signing: no chance of changing the season, but no chance of becoming a financial or tactical burden either. In a context where Repesa needs someone to round out the rotation without breaking the existing structure, this was the most logical choice.

Ulm promoted a young player from the B team, sacrificing experience to keep costs minimal and maintain team identity. This is a culturally rooted decision more than a tactical one: Ulm has always prioritized developing young players from its academy, and Heckel is a direct product of that philosophy. With Polas Bartolo's return as the only real solution to their depth problem, internally promoting a young guard made sense on both financial and personnel grounds.

In the broader European basketball picture, both signings reflect a truth I have observed since 2026: European basketball is increasingly polarized between a small group of "buy-the-star" clubs and a majority that "build from within or from the mid-market." EuroCup concentrates many of the latter, and contracts in the 100,000 to 300,000 euro range per season, plus internal promotions from B teams, are the actual backbone of this competition. The young-player price bubble is bursting not just in the NBA but in Europe too: 100 million euros for a player who has not yet played 50 top-level games is a naked gamble, and neither Napoli nor Ulm could afford that gamble.

I spent eight months in 2026 building the only "basketball without spectators" dataset in Vietnam, and the biggest lesson I took from that was that the data-collection context matters more than the raw number. A contract that looks mediocre on paper can create real, if small, value if it sits in the right tactical context and the right point of the season. That is how I read both Tarczewski and Heckel: not blockbuster signings, but signings that fit each team's specific context.

Contrarian Angle

There is another reading of both signings that few outlets mention: both Tarczewski and Heckel have clear limits in taking Napoli and Ulm beyond the group stage, despite the tactical fit I have just laid out.

Tarczewski, however well he fits Repesa's system at a basic level, will not solve two core Napoli problems in the Group C race: the lack of a secondary creator beyond Luwawu-Cabarrot, and the lack of perimeter defense against teams with multiple stable shooters. Against Valencia, Napoli's defense will face situations Tarczewski cannot handle, such as clear-out five-out spacing, or shooters with strong screen-escape skills.

Heckel, by contrast, will not solve Ulm's real backcourt depth problem. He is a temporary patch until Polas Bartolo returns, and the question is whether Polas Bartolo returns this season at all. For knee injuries, the typical recovery timeline to EuroCup intensity is six to nine months, meaning April to July next year, by which point the season is essentially over. Heckel will be asked to carry a role heavier than his capability for most of the remaining schedule.

Both signings are good at stabilizing the rotation and avoiding risk, but neither can create a breakthrough. In basketball, the final shot is decided 40 minutes earlier, and these two signings, however tactically correct, are not that season-defining shot. Individual glory is the paint, the system is the wall, and neither Napoli nor Ulm has yet built one tall enough to resist the top opponents in Group C.

Takeaway

When the stadium is empty, I begin to hear the real sound of the game, and in this case, the "stadium" is the transfer-office window, where every move is measured in euros and minutes rather than in cheers or headlines.

The question I am left with after reviewing both signings is whether Napoli and Ulm can hold their form through the middle stretch of the campaign when the bigger teams in Group C are ready to push their spending for the second leg. In basketball, the last shot is decided 40 minutes before it goes up, and signings like Tarczewski and Heckel are exactly that first shot in a long journey for both clubs. We will have to wait until March to see whether it misses or drops in.

Analysis is not about proving I am right; it is about letting the game speak for itself, and in this case, the game has not yet started.
