Wow, what an interesting trade. I don't like the deal, BUT I will say that it is a gamble that certainly could payoff. I don't love Green, but he has upside and he is young. It's very tough to predict how he will fit in here and how he will respond to the pressure of playing in an environment of championshipship expectation. I haven't heard too many people talk about this aspect of the trade, but imo the most important factor is Green himself. It's not a fait accompli that he plays well here, and it's not a fait accompli that he doesn't excel here, either.
Other factors, in order:
1. Does Murphy sign here? He can rebound, shoot, and score, but he can't defend. I don't love Murphy but we need his rebounding desperately. In certain matchups vs. certain teams, he could really help us.
2. Jermaine O'Neal. I may be in the minority, but I like JOs game a lot. If he can get back on the court and play in a limited role, he can defend, block shots, rebound, and score a little. His health is a big if, though.
3. Sheed. Is he in shape? Do the Celtics even want him? Does Sheed even want to come back? IF he is in shape, he could help.
edit: I forgot to mention Kristic because the guy pretty much sucks. If he is going to play like 5-10 minutes a game (or less), fine...he is a good offensive player. Other than that, he is a stiff. I hope they don't play him much.
