I really liked BG also, the problem was, at the Pistons there was a logjam of undersized guards and they all got time, it was baffling, once they realised BG wasn't going to win them too many games, he moved to a reserve role.
I still think he was one of the best 3 point and jumpshots in the game. I think he can really help somebody next year, I'm sure he could get 2-3 mill per season. He's done very well moneywise.
Another mistake by the Pistons was Villanueva, I can't believe he still plays for them, what a waste of money.
