Kyrie is young, it seems unfair to think he cant add any nuances to his game. In the Bron Ball system all that is asked of him is to score and take game winning shots. Dude is talented, I think we can see improvement on the defensive side as well as seeing his assist numbers go up if he is asked to do that. I think a move to the Spurs or even the Pelicans could change the perception we have of Kyrie's game.Kyrie is a scorer period, what system is magically going to make him a better defender and playmaker for others.
It's not too late for Kyrie, he can get better but not by playing Bron ball
