Some people just don’t change.

Jazz rookie and controversial former Duke star Grayson Allen got into his first NBA tussle during a summer league game Thursday night.

Allen and Hawks rookie Trae Young clashed early in the second half while Allen was guarding Young at the top of the arc. When Young stepped back and rose to shoot, his arms tangled with Allen’s and he lost the ball.

Young pushed Allen toward the floor and Allen fought back. Teammates quickly restrained them and the referees gave them both technical fouls.

“That’s not the first time Grayson has gotten tangled up with someone,” Young told reporters after the game, “but it’s not the first time and last time I’m going to get tangled up with someone. It’s going to happen. This is the NBA. It’s going to be a physical game. Grayson is a physical player. I’m a physical player.”

Allen became one of the most controversial players in college basketball after earning a reputation for tripping, elbowing and stomping on his opponents.

He was suspended indefinitely in December 2016 when he was caught tripping Elon guard Steven Santa Ana — though Duke coach Mike Krzyzewski lifted the ban after only one game.

Neither player impressed in the summer league matchup. Allen was 2-of-13 from the field and Young didn’t do much better, going 3-of-16 after a similarly dreadful debut Monday night.
