My perspective is that talent wins games. We are more talented with him than without him?
The other players you mentioned:
STAT was horrible last year. What if injuries have taken their toll and he's never the same again? Looks like LJ all over again. Good/decent but not great.
Melo struggled with his weight. Kind of a bad sign for a superstar player. Him getting in the best shape of his life is imperative. BUT, what if he cant? Another thing. when Melo is shooting 5-20 at the start of the 4th quarter (like he did plenty of last year) Wouldnt it be nice to have some one capable of taking over a game? Like Lin? Is Felton going to do this? Kidd?
