I don't think he's a coward, quitter, or anything like that. He showed incredible heart this playoffs after everything that went down. Granted, I only watched the play-by-play last night and not the game itself.
However, I do think this playoffs has cemented his status as a non-max player, or at least it should have for us with Fultz incoming. His size just makes him too easy to ganeplan for, and his defense is really just atrocious, eveb beyond his lack of size.
I still hold that IT is best suited as a 6th Man of the Year type scoring spark plug off of the bench, and I think it's pretty clear he can't be the best player on a contending team. Being a starter and our best overall option offensively, he's just too easy to gameplan for and take advantage of defensively.
