The basketball world was buzzing after the EuroBasket 2025 semifinals on September 12, when Turkey pulled off a stunning upset, defeating Greece 82-74 to advance to the finals for the first time in 24 years. At the centre of the drama? None other than Milwaukee Bucks superstar Giannis Antetokounmpo, the two-time MVP and perennial NBA Defensive Player of the Year candidate, who was held to a shocking 12 points on 6-of-13 shooting. For a player who is presented as unguardable throughout his career—averaging over 25 points per game in the tournament up to that point—this was a defensive clinic that exposed vulnerabilities in the Greek Freak’s game.

Turkey, under coach Ergin Ataman, didn’t just defend Giannis; they dissected him with a blend of physicality, teamwork, and tactical precision. This wasn’t a fluke—it was a blueprint that echoes strategies we’ve seen (and debated) in the NBA for years. Three years of early playoff exits, three years of losing even in the regular season against teams that care enough to defend him like this.

The EuroBasket Breakdown: Turkey’s Defensive Symphony

Greece entered the semifinal as favourites, largely on Giannis’s reputation. By sheer luck of the bracket however Greece had not faced any serious opponents. Giannis skillfully avoid playing against Nurkic because he knew what would happen. (They lost anyway, Giannis avoided looking foolish though.) The recipe is simple:

1. Disrupt the Delivery: Pressure the Perimeter

Turkey’s first line of attack was simple but ruthless: make it hard for Greece to get the ball to Giannis. Guards Sehmus Hazer and Shane Larkin (yes, the ex-Celtics sharpshooter now starring for Anadolu Efes) hounded the inbounders and ball-handlers, using quick hands and relentless pressure to force 12 turnovers in the first half alone. Cedi Osman, the NBA veteran forward, chipped in by switching onto Giannis in open court, denying easy touches and forcing him to receive the ball further from the rim than he prefers.

This tactic preyed on one of Giannis’s subtler weaknesses: his ball-handling under duress. At 6’11” with a long stride, he’s a transition monster, but Turkey’s transition defence was lockdown—limiting fast breaks and keeping Greece in a half-court grind. As Alperen Sengun later noted in a post-game interview, “We knew if we let him bring the ball up freely, it was over. So we trapped early and often.”

2. One-on-One Anchor with Help on Demand: Osmani’s Heroics

Enter Ercan Osmani, Turkey’s 6’10” power forward and the unsung hero of the night. Osmani drew the primary assignment, bodying Giannis in the post and contesting every move with physicality that matched the Freak’s ferocity. But this wasn’t hero-ball defence; it was a relay. Whenever Giannis put the ball on the floor inside the three-point line, the paint collapsed. Sengun, the Houston Rockets’ rising star centre, rotated over as the “wall,” swatting at drives and contesting lobs without leaving his man exposed.

Shane Larkin summed it up perfectly in a post-game breakdown: “The plan was to collapse whenever he raised that ball to drive. Force the kick-out, then rotate hard on the perimeter. We accepted threes from their guards—guys like [Thomas] Walkup aren’t lights-out shooters.” This “shrink the floor” approach turned Giannis into a passer and like Sengun had said before the game “Giannis is not a great passer.”

3. Zone and Traps: The Triple-Team Fortress

When Giannis did touch the ball in his sweet spot—the low block or mid-post—Turkey flipped the script to a hybrid zone. Double-teams (often Osman and Sengun) quickly escalated to triples, with a third defender (frequently Osman circling back or Hazer digging in) forming what one reporter called a “fortress wall.” Passing lanes were clogged, leading to strips and turnovers. Physicality was key: Turkey played with NBA-level bump-and-turn, wearing Giannis down over 35 minutes.

The result? Giannis, who thrives on momentum and space, looked frustrated—good for just 12 points, 12 rebounds, and those 5 assists. Turkey’s bench erupted after a key sequence in the third quarter where a triple-team forced a kick-out that sailed wide, sealing the momentum shift. It was defense as performance art: collective, adaptive, and unrelenting.

Why This Works in the NBA: Timeless Principles Meet Pro Pace

EuroBasket might play at a slower tempo than the NBA’s breakneck speed, but Turkey’s blueprint is straight out of the league’s defensive playbook. Giannis’s dominance—elite athleticism, length, and finishing—makes him a matchup nightmare, but he’s not invincible. His game relies on driving lanes, transition opportunities, and post-ups, all of which can be neutralized with smart team defense. Here’s why Turkey’s tactics aren’t just FIBA-specific:

The “Wall” Strategy: A Proven NBA Staple

Coined during the 2021 playoffs when the Heat and Nets tried (and sometimes succeeded) in slowing Giannis, “The Wall” involves funneling him baseline or middle with on-ball pressure, then crowding the paint with help defenders. Turkey executed this to perfection, much like the Miami Heat’s 2020 bubble run, where Bam Adebayo and a rotating cast of bigs forced Giannis into 5+ turnovers per game. In the NBA, where spacing is tighter due to better shooters, teams live with contested threes from role players (e.g., Bucks’ Pat Connaughton) rather than letting Giannis bulldoze to the rim.

Physicality and Rotations: Exploiting Fatigue

The NBA’s 82-game grind amplifies Turkey’s physical approach. Giannis averages 34+ minutes per game; constant doubles wear him down, forcing passes that expose slower rotations. Data from the 2024-25 season shows Giannis’s efficiency dips 15% against teams that trap him 20%+ of possessions (per Second Spectrum tracking). Turkey’s zone hybrids mirror what the Warriors used in their March 2025 win over Milwaukee, where Draymond Green orchestrated rotations to limit Giannis to 18 points.

Transition Denial: The Silent Killer

FIBA rules limit fast breaks slightly, but the principle holds: Deny outlet passes and force half-court sets. In the NBA, where Giannis scores 40% of his points in transition, teams like the Celtics use length (Tatum, Brown) to mirror this, dropping Milwaukee’s transition efficiency by 12 points per 100 possessions in recent matchups.

In short, Turkey’s win proves that with discipline, no star is untouchable—especially one whose jumper (still a work in progress at 29.5% from three in 2025) keeps defenses honest but not terrified. After all as I have explained at length and with much statistical proof, Giannis has no mid range when it matters.

NBA Defenders Who’ve Cracked the Code: A Hall of Fame Lineup

Over Giannis’s decade in the league, only a select few have consistently turned him mortal. These aren’t just stat-line suppressors; they’re tacticians who force the Bucks to play “away” from their star. Here’s a rundown of the most effective, based on playoff and regular-season matchups (points per possession allowed under 1.00, per NBA Advanced Stats):

Bam Adebayo (Miami Heat) – The Gold Standard

Bam’s the closest thing to a 1v1 kryptonite. In the 2020 and 2023 playoffs, he held Giannis to 22.4 PPG on 48% shooting, using his lateral quickness to stay in front and strength to absorb contact. Fun fact: Adebayo’s the only defender who’s outscored Giannis in head-to-head minutes while forcing 2.1 turnovers per game. Why it works? Bam funnels him without help, buying time for rotations.

Joel Embiid (Philadelphia 76ers) – The Post Enforcer

Embiid’s size (7’0″, 280 lbs) and IQ make him a post-up nightmare. In 2023 Eastern Conference Semis, Philly’s scheme with Embiid as the anchor dropped Giannis to 19.8 PPG. He’s physical enough to bang without fouling and mobile enough to recover on drives—key against Giannis’s euro-steps.

Draymond Green (Golden State Warriors) – The Chaos Conductor

Green’s not matching Giannis’s athleticism, but his brain is unmatched. In the Warriors’ 104-93 dismantling of the Bucks in March 2025, Draymond guarded him straight-up for 28 minutes, limiting him to 18 points on 7-18 shooting. It’s all about positioning: Green pressures full-court, funnels baseline, and communicates traps like a quarterback. Career vs. Giannis: Holds him under 1.05 PPP.

Rudy Gobert (Minnesota Timberwolves) – The Rim Guardian

Three-time DPOY Gobert’s length (7’9″ wingspan) clogs lanes. In 2024 playoffs, Minnesota’s “Gobert Wall” (with Jaden McDaniels) restricted Giannis to 24 PPG on 52% eFG%. Rudy’s not quick enough for full games, but in drop coverage, he erases lobs and weak-side help.

P.J. Tucker (Formerly Clippers/Raptors) – The Gritty Veteran

Tucker’s the ultimate “annoyance” defender. During the 2019 Raptors run, he bodied Giannis into 22.3 PPG on inefficient shots. His low center of gravity and hand-fighting disrupted rhythm—perfect for half-court sets.

Honorable mentions: Al Horford (Celtics’ zone wizardry in 2022 ECF), Jayson Tatum (versatile switching), and OG Anunoby (Raptors’ length in isolation). Hell, even the much shorter Dillon Brooks last season wiped Giannis on his own!

The Freak’s Evolution and the Defender’s Edge

Turkey’s EuroBasket triumph wasn’t just a win—it was a reminder that basketball’s a team sport, even against unicorns like Giannis. By disrupting flow, collapsing space, and embracing the grind, they turned a supernova into a shooting star. In the NBA, where schemes evolve daily, expect more coaches to dust off this playbook as the Bucks chase another ring.

What’s next for the Greek Freak? A sharper jumper? Better pick-and-roll vision? It doesn’t seem like he has added anything at all to his game all these years. More and more NBA players will just pull him apart like Turkey did. Bucks’ fans get confused because in easy games in the regular season most teams don’t bother. Why risk injury when so many times the officials don’t even give you the clear offensive foul Giannis commits? But when it counts? Three first round exits say “Giannis ain’t got it no more”.
