I guess depending on who's point of view you take.
I mean it could be said that Vince wasn't put into a position to succeed because SMitch didn't let him be the player he is and have the ball in his hands like he was accustomed to.
Then Vince's lack of effort on the floor hurts too, but what if SMitch made the system to be more to Vince's liking?? would he have played better?? maybe, maybe not?!?!
no one will ever know.....
