To the OP, who seems to forget pretty easily: you are making the wrong question. Should be: Did Hood & Kanter give up on us too soon?
Moron Kanter wanted a bigger role, even though he was playing 27MPG. He thought he was being slow down. And he demanded a trade.
Same with Hood, who thought he was a first or second offensive option. Plus, he wanted big money. According to several reports (Tony Jones among them), the situation got really bad in the locker room. So we shipped him out for a more durable, gritty player in Crowder (not as good as a shooter though). Had Hood accepted a 6th man role (and that type of money), he would probably still be here.
Their career trajectories, as Favors said some days ago, shows that the grass is not always greener elsewhere.
