Giannis Antetokounmpo was coming out of a frustrating loss

The altercation with the fan came after a defeat against Los Angeles Lakers. Team with the two best records in the NBA were coming into the game where the Lakers eventually prevailed.

LeBron James led the Lakers in the win with 37 points, eight assists, eight rebounds. Antetokounmpo admitted he was facing one of the best players in the league after the 113-103 loss.

“I think it’s always good playing against one of the best players in the league,” Antetokounmpo said of James. “Like … you can feel greatness. All of this I’ve said in the past: That’s what I wanna be. Obviously, he’s one of the best players in the game. Really smart; you cannot be B.S.’ing against him. He’s gonna come at you. You gotta be ready to go, you gotta be ready to fight against him.

“I think we were ready to fight. I think we did a good job. But at the end of the day, he’s going to get his shots up, and he’s going to get his teammates as well. He’s LeBron James — what can I say?”
