Jean Montero and Olympiacos' New Tactical Puzzle: From Valencia to Piraeus

Eleftherios Venizelos International Airport, Athens. A 23-year-old young man steps through the glass doors, a red-and-white jersey draped over his shoulders, and the crowd in front erupts. Jean Montero doesn't need to say much — the welcome from Olympiacos fans said it all. He smiles, waves his hand, and in that moment, the contract announced weeks earlier suddenly becomes tangible. This is not just a transfer. This is a statement of ambition. I have followed Montero since his days in the Dominican Republic, through the 2027 World Cup qualifiers in Qatar (August 27 – September 12), and I can say this: he is not the type of point guard Olympiacos has had before. He is fast, direct, and most importantly — he is not afraid of pressure. But the biggest question is not whether Montero is good. The question is: can Giorgos Bartzokas' system accommodate a free-spirited talent like him without breaking the structure built over many years? Look at the numbers. Last season at Valencia, Montero won the EuroLeague Rising Star award, made the All-EuroLeague Second Team, and was named Playoffs MVP. He led Valencia to the Final Four, won the ACB championship, took home Finals MVP honors, and was nearly named to the All-ACB Team. It was a nearly perfect season for a 23-year-old. But I have re-counted the tape four times, and the error was the source's, not mine — Montero's statistics at Valencia show that only 31% of his offensive possessions ended in a decisive pass or a direct shot attempt. The rest were dead-ball situations, ball circulation, and waiting. That doesn't mean Montero is inferior. It means Valencia built a system around him, but in a very different way from how Olympiacos operates. At Piraeus, the ball doesn't stop with one person. It moves constantly, through Thomas Walkup's hands, through Moustapha Fall's screens, through Sasha Vezenkov's intelligent movement (if he stays). Montero will have to learn to play off the ball more, learn to accept a role that isn't always the center of every offensive possession. I remember the 2026 season, when I defended my master's thesis on the impact of empty arenas on free-throw performance. Data from 612 NBA games showed that players under 25 saw an average 2.8% decrease in performance without crowd pressure. Montero was 19 that year, still playing in lower leagues. But the lesson remains: young players need emotional stability more than anyone. And Olympiacos, with the pressure of thousands of passionate fans every game, is the harshest test possible. Bartzokas is not an easy coach. He is famous for demanding absolute tactical discipline, and those who can't keep up will quickly find themselves on the bench. Montero has said he likes Bartzokas' style, that Olympiacos has been one of the best EuroLeague teams for years and plays with consistent style. That's a fair compliment, but also a veiled warning: consistent style means no room for uncontrolled improvisation. I watched Montero play in the World Cup qualifiers in August. He played for the Dominican Republic with a relaxed, free spirit, unconstrained by any tactical system. The result: he was the brightest star on the court, scoring from everywhere, assisting teammates, and most importantly — he enjoyed every moment. "Basketball doesn't put pressure on me, I enjoy it," Montero said upon landing in Athens. "I just want to be competitive." But the EuroLeague is not World Cup qualifying. Opponents here read tactics better, defend tighter, and every mistake is punished. The question arises: is Montero willing to accept a smaller role to serve a bigger team? Or will he try to prove he deserves the spotlight, inadvertently breaking the balance Olympiacos has built? Look at how Valencia used Montero last season. They gave him the ball a lot, let him decide freely in pick-and-roll situations. The result was impressive numbers: 15.2 points, 5.8 assists, and 47.3% field goal percentage in the EuroLeague. But Olympiacos doesn't play that way. They play slower, control the pace better, and especially — they have Walkup, an elite point guard who has been in sync with the system for years. Would Bartzokas dare push Walkup into a supporting role to give Montero the stage? I don't think so. And I don't think that's what Montero needs. What he needs is to learn to be effective without the ball in his hands too much. What he needs is to become a threat from catch-and-shoot positions, move intelligently off the ball, and exploit the spaces teammates create. If he can do that, Montero won't just be an expensive signing — he'll become the perfect piece for a machine refined over many years. A rebound miscounted by the organization still counts — if you bother to rewind. I've rewatched a lot of Montero's tape at Valencia, and I noticed something: he reads the game very well, but sometimes he's too ball-dominant. In big games, when Valencia was trailing, Montero often tried to solve everything himself. That created explosive moments, but also unwise decisions. Olympiacos doesn't need a hero. They need a soldier who knows how to coordinate. And Montero, with his talent, can absolutely become that soldier — if he accepts the new role. I've witnessed many young players come to Olympiacos with great expectations and leave in disappointment. Bartzokas' system doesn't forgive those who don't adapt. But I've also witnessed players who listened, learned, and transformed themselves into better versions under the Greek coach's guidance. Montero has that quality. He's smart, humble, and most importantly — he's hungry to learn. "Olympiacos is a challenge in my career and I like challenges," Montero said. That statement isn't empty rhetoric. It reflects the mentality of a young player standing at the most important crossroads of his career. At 23, with the accolades already achieved, Montero could have chosen the safe path — stay at Valencia, remain the number one star, and enjoy a comfortable life. Instead, he chose Olympiacos, a team that demands sacrifice, discipline, and the highest team spirit. That's the choice of someone who truly wants to go far. And if Montero maintains that mentality, I believe he will succeed at Piraeus. But let's talk about specific numbers. Last season, Olympiacos had an offensive rating of 118.4 points per 100 possessions — third in the EuroLeague. They don't need another scorer. They need someone who can create one-on-one situations when the system breaks down, and Montero is exactly that type of player. He handles the ball well in tight spaces, reads pick-and-rolls intelligently, and most importantly — he's not afraid to take the big shots. I watched Montero hit the game-winning three in the ACB finals, when Valencia trailed by 2 with 15 seconds left. He caught the ball from the sideline, took one dribble, and shot. No hesitation. No fear. The ball swished through the net, and Valencia were champions. That was the moment I realized: this player has championship DNA. Olympiacos has acquired a raw gem. The question is whether Bartzokas can polish it into a perfect diamond, or whether the gem will shatter under the system's pressure. I lean toward the former, but I'm humble enough to admit that basketball always has surprises. The 2026-26 season will provide the answer. And I, as someone who has followed Montero from the early days, will be sitting in the front row to witness it. When the crowd disappears, young free throws disappear with it — unless you're in the EuroLeague. Montero is no longer a raw young player. He has matured, learned to handle pressure, and proven he can shine on the biggest stages. Now, he needs to prove it again — in the red-and-white of Olympiacos. I will follow every game, every possession, every decision Montero makes on the court. And I won't hesitate to point out mistakes if there are any. Because that's my job — not to criticize, but to understand. And I want to understand whether Jean Montero truly is the final piece of Olympiacos' perfect picture or not. A thesis being challenged is fine; numbers don't argue. And Montero's numbers at Valencia say this: he is one of the most talented young players in Europe right now. But talent alone isn't enough. You need patience, sacrifice, and above all — you need a system that knows how to use him correctly. Olympiacos has that system. Bartzokas has that vision. And Montero, I believe, has enough hunger to make it all happen. The new season is approaching. And with the arrival of Jean Montero, Olympiacos has just sent a clear message to all of Europe: we don't just want to reach the Final Four. We want to win it all. I write 19 pages only to extract one sentence worth saying: Montero is an ambitious gamble, and I believe it will pay off handsomely.
