Giannis Antetokounmpo is one of the NBA’s most well known and loved players, but he’s had too many moments in big games where mistakes impacted the Milwaukee Bucks’ chances of winning. Pinpointing specific errors that definitively “cost” a game can be tricky—basketball is a team sport, and outcomes often hinge on collective performance—but there are notable instances in crucial matchups where Giannis’s decisions or miscues played a significant role in a Bucks loss. I did a different blog post with the stats (check it out here) but I thought I should remind you all of some stand out dumb plays which are characteristic.
Tonight was a characteristic example. With the Bucks down 104-103 and 30 seconds left, Giannis fouled Alperen Sengun in the backcourt—an unnecessary play given the situation. Sengun made both free throws, pushing the lead to three, and Houston held on to win 106-103. Giannis had 34 points and 14 rebounds, but that low-IQ foul shifted the game’s outcome, as the Bucks couldn’t recover. It was a pivotal mistake, reflecting fan frustration with his decision-making in crunch time. Because he does it all the time.
One glaring example comes from the 2023 playoffs, Game 5 of the Eastern Conference First Round against the Miami Heat. The Bucks, up 3-1 in the series, lost 128-126 in overtime at home, getting eliminated by the 8th-seeded Heat. Giannis struggled at the free-throw line, going 10-for-23 for the game. In the clutch, with the Bucks down by two in the final seconds of regulation, he missed two free throws that could have tied it up. Miami’s Jimmy Butler then forced OT with a buzzer-beater. Giannis finished with 38 points and 20 rebounds, but those misses—especially given his season-long 64.5% free-throw shooting—shifted momentum and left the Bucks vulnerable. The Heat sealed the upset, and Giannis’s free-throw woes were a key talking point.
Another instance is from the 2020 Eastern Conference Semifinals, Game 4 against the Heat. The Bucks were down 2-1 in the series, and this game was pivotal to avoid a 3-1 hole. Late in the fourth quarter, with the score tight, Giannis committed an offensive foul by charging into a defender while driving to the basket. He finished with 19 points before exiting early due to an ankle injury, but that foul—his fifth—sapped Milwaukee’s momentum at a critical juncture. The Heat won 115-104, taking a commanding series lead. Miami’s defensive scheme, often called the “wall,” baited Giannis into physical drives, and his decision to barrel through rather than pass or pull up was a costly misjudgment. The Bucks lost the series in five.
In the 2019 Eastern Conference Finals, Game 4 versus the Toronto Raptors, Giannis’s play contributed to a turning point in the series. Milwaukee led 2-1, but Toronto stormed back to win 120-102. Giannis scored 12 points on 5-for-16 shooting and fouled out with over seven minutes left after picking up his sixth foul on a questionable defensive reach. His absence down the stretch let Toronto pull away. He also turned the ball over seven times, including sloppy passes under pressure from Kawhi Leonard and the Raptors’ swarming defense. The Bucks dropped the next two games, and the series slipped away. Giannis’s inability to stay disciplined and on the floor was a factor in squandering their lead.
Finally, in the 2021 NBA Finals, Game 5 against the Phoenix Suns—while the Bucks ultimately won the title—Giannis nearly cost them a crucial win. Up 3-1 in the series, Milwaukee led 108-107 with under a minute left. Giannis, guarding Devin Booker, overcommitted on a pump fake, fouling Booker and sending him to the line. Booker made both free throws, giving Phoenix a 109-108 lead. Giannis redeemed himself with a block on Deandre Ayton seconds later, preserving a 123-119 victory, but that defensive lapse could’ve swung the game and the series momentum. It’s a rare Finals example where his error didn’t fully cost them, but it teetered on the edge.
These moments—free-throw misses, offensive fouls, turnovers, and poor defensive decisions—showcase recurring themes in Giannis’s game: occasional recklessness driving to the rim, struggles with free throws in clutch spots, and lapses in discipline under pressure. Context matters—teammate injuries, coaching decisions, and opponents’ brilliance (like Butler’s 2023 heroics)—also shaped these outcomes. Most Bucks’ fans use them to excuse Giannis. But in these high-stakes games, Giannis’s miscues were the real difference-makers.
Everyone acts as if he is improving. He isn’t. If anything the difference between what Giannis thinks he can do and reality now has an even bigger gap. Doc Rivers knows and tries to keep him out. But he still finds a way to mess up high pressure games.
Here is his box score
Yeah, as usual. Basically only stat padding defensive rebounds. As usual the wasted 3 point attempt. And particularly bad shooting.
