I like him less and less as time goes on. I've noticed on offense when he makes a move, a lot of times his upper body goes forward and into the defender, while his legs lag behind like they are stuck in quicksand...and he ends up just throwing the ball toward the basket.
Another thing that as a very bad sign to me are his facial expressions. He doesn't get that angry look that the great players get when they are frustrated. He gets that whiney whimpy mentally soft look like Gerald Green makes after a turnover or Vince Carter used to make when he thought he was fouled. He always literally looks like he is about to cry. In no way would I want a guy like that to be the centerpiece of the Celtics.
As talented as Cousins is, he is a quitter and one of the worst competitors in the league.
