Replays show that Antetokounmpo's left foot touches the baseline as he drives, and though a referee was standing right behind him, no whistle was blown.
The Milwaukee Bucks star needed every bit of lift he could get, muscling on Thunder star Russell Westbrook just enough to get the dunk to fall through for the game-winner with 1.3 seconds left to lift the Bucks to a 97-95 win Friday night at Chesapeake Energy Arena.
Thunder players and their coach seemed resigned to their fate.
The play was not reviewed at the time.
Antetokounmpo said he hadn't yet seen the replay and wasn't aware that he'd stepped out of bounds. Everybody knows that. I didn't get a chance to personally see the replay. The idea that the officials could review if a player's foot in on the arc and the bucket is a 2 or a 3 during the second quarter, but they couldn't review the Greek Freak stepping out of bounds, is just wrong.
"I asked them if they could review it and they said they could not review it", he said. "That's the only explanation I got". The game-winning play would have been brilliant... had Antetokounmpo not clearly skipped out of bounds before the dunk with the referees going blind to the situation.
The Bucks led the Thunder by as many as 22 in Oklahoma City, but Westbrook led a furious charge to keep OKC in the game. "We can't do nothing about that at this point, so we might as well forget about it and move on and get ready for. who do we play Sunday?"
Khris Middleton scored 20 points and John Henson added 18 points for the Bucks, who completed a sweep of the Northwest Division's top two teams on consecutive nights.
The Thunder saw it in the moment, but the officials missed the call. It was Abrines' fifth start of the season, but he was scoreless in 10 first-half minutes.
