When Vassilis Spanoulis took the reins of the Greek national basketball team for the 2024 Paris Olympics, he faced a tantalizing challenge: how to maximize Giannis Antetokounmpo, a two-time NBA MVP and global superstar, in a FIBA setting. Greece’s return to the Olympics after a 16-year absence demanded a bold approach, and Spanoulis—a EuroLeague legend known as “Kill Bill” for his clutch tenacity—delivered one. His deployment of Giannis during the Olympic Qualifying Tournament (OQT) in Piraeus and the Paris Games diverged significantly from how Giannis is utilized with the Milwaukee Bucks, reflecting the constraints and opportunities of international play. Giannis has always struggled playing outside the NBA. Let’s break down the key differences and why they mattered.
Positional Fluidity: From Power Forward to Center
With the Bucks, Giannis typically operates as a power forward in a structured NBA system under coaches like Mike Budenholzer and now Doc Rivers. Milwaukee’s lineups often pair him with a traditional center—Brook Lopez or Bobby Portis—allowing Giannis to roam the perimeter, initiate fast breaks, or attack downhill off pick-and-rolls. Lopez’s floor-spacing (35.4% from three in 2023-24) pulls opposing bigs away from the paint, giving Giannis clean driving lanes in Milwaukee’s “five-out” or “four-out-one-in” schemes. They even let him bring down the ball hunting the easy run and dunk which is ludicrous since he is not a good ball handler.
Spanoulis, however, embraced greater positional flexibility. Facing tougher defensive congestion in FIBA play—where zones and physicality reign—he occasionally slid Giannis to the center spot, as seen in Greece’s 77-71 win over Australia. Without a Lopez-like shooter (Greece’s bigs, like Georgios Papagiannis, were less perimeter-oriented), Spanoulis leaned on Giannis’ speed and strength to exploit mismatches against smaller lineups or slower traditional centers. This shift amplified Giannis’ role as a screener and roller, a contrast to Milwaukee, where he’s more often the ball-handler in pick-and-rolls with Damian Lillard or Khris Middleton. In Paris, Giannis averaged 25.8 points on a staggering 67.8% from the field, showcasing how Spanoulis weaponized his interior presence against FIBA’s compact defenses. Giannis is for sure one of the worse screeners in the NBA so you can never really rely on him for that though.
Offensive Focal Point vs. Shared Load
In Milwaukee, Giannis is undeniably the Bucks’ alpha, averaging 30.4 points per game in the 2023-24 season, but the offense isn’t solely his to carry. With Lillard’s elite scoring (24.3 PPG) and Middleton’s mid-range reliability in the past, the Bucks distribute the offensive burden, often running set plays or isolations for their stars. Budenholzer’s “Giannis Wall” counter—surrounding him with shooters—evolved into Rivers’ more dynamic pick-and-roll-heavy approach, balancing Giannis’ drives with outside threats. The much under rated role of this in the championship run in the NBA has confused many. They focus on Giannis and forget he had a legit super team in order to win the chip.
Spanoulis, by contrast with less star power as Nick Calathes was a playmaking wizard (10.5 assists in the OQT), but not a scoring threat like Lillard. So Spanoulis leaned hard into Giannis’ ability to dominate one-on-one and draw multiple defenders. Greece’s offence often started with Giannis at the top of the key, bulldozing through contact or kicking out to shooters like Thomas Walkup when doubled. During the OQT, Greece shot 43.5% from three (54-for-124), a testament to Spanoulis’ strategy of spacing the floor around Giannis, but in Paris, teams like Spain countered with a “Box and 1,” daring others to beat them. Greece lost when Giannis met up with teams that could stop him. That simple.
Defensive Role: Help Defender vs. Point-of-Attack Stopper
Defensively, the Bucks often conserve Giannis’ energy, using him as a roving help defender rather than a primary on-ball stopper. Sure he stat pads with easy defensive rebounds but he is no longer in his DPOY years and it shows in all advanced stats. Lopez or Portis handle rim protection, while Jrue Holiday (pre-trade) or Malik Beasley or whoever else they have to chase guards. Milwaukee rarely asks him to lock down elite wings or guards full-time, preserving him for offence. It’s almost as if the entire organisation is more focused on his stat padding.
Spanoulis, however, demanded more defensive versatility. With Greece’s roster lacking Milwaukee’s depth, Giannis toggled between help defense and stepping up as a vocal leader. After the 86-79 loss to Canada—where Giannis dropped 34 points but struggled defensively against Shai Gilgeous-Alexander’s 21—Spanoulis publicly challenged him to elevate his effort, a stark contrast to the Bucks’ more measured approach. Against Germany in the quarterfinals (76-63 loss), Giannis faced Dennis Schröder and Daniel Theis, often switching onto quicker guards or battling in the post. While teammates like Calathes and Kostas Papanikolaou took tough assignments, Spanoulis relied on Giannis’ physicality to disrupt plays, even if his 6.3 rebounds per game in Paris lagged behind his NBA norm (11.5). There are no two ways to look at this: Giannis simply struggles in high pressure situations.
Pace and Physicality: FIBA Grit vs. NBA Flow
The Bucks thrive in transition, where Giannis’ coast-to-coast gallops are a staple—think his iconic Eurostep dunks. Milwaukee’s pace (100.4 possessions per game in 2023-24) suits his freakish athleticism, and NBA rules—wider courts, defensive three-second violations—give him room to operate. Spanoulis, however, adapted to FIBA’s slower, grittier style (no defensive three-second rule, tighter paint), where Giannis faced constant physicality. Teams like Canada and Spain threw “walls” of defenders at him. It worked because Giannis has no bag and no other options in his game.
Spanoulis countered by emphasizing ball movement (Calathes’ assists kept Greece humming) and using Giannis as a decoy when needed, a departure from Milwaukee’s reliance on his transition scoring. In the Australia game, Giannis’ presence in the post drew defenders, opening cuts and kickouts—a nod to Spanoulis’ EuroLeague roots, where team play trumps individual heroics.
Why the Difference?
Spanoulis’ approach was born of necessity and philosophy. Greece lacked Milwaukee’s supporting cast—no Lillard to share the scoring, no Lopez to stretch the floor. Spanoulis, a competitor who thrived under pressure as a player, saw Giannis as the key to reviving Greece’s basketball pride, pushing him to lead by example in ways the Bucks, with their deeper roster, don’t require. FIBA’s rules and physicality also forced Spanoulis to get creative, using Giannis’ size at center and banking on his relentlessness to overcome officiating disparities.
In Milwaukee, Giannis is a cog in a well-oiled machine, optimized for an 82-game season and playoff grind. With Greece, he was the machine—every gear turned around him. Spanoulis’ vision nearly worked: Greece qualified for Paris and pushed top teams, falling just short against Germany. The contrast highlights not just tactical differences but a mindset: Spanoulis coached Giannis like a warrior king, while the Bucks treat him as a prized asset in a broader kingdom. Both work—but Paris showed Giannis’ ceiling. He cannot even comprehend advanced basketball plays and for sure he cannot react fast enough in high intensity basketball at the highest level.
