Don't know why everyone so many people are in love with this guy.
Pretty good rebounder (not great), runs well, shoots terribly (considering how confident he is in taking them), and is a very good individual defender. He's a fringe all-star making a lot of money.
Maybe Green won't become a better player than Smith, but he should be a more complimentary player to this team. For the price Green is costing us and the salary I'm sure Smith will be looking for, I don't see the point. Add in losing other assets (Bass/picks/whatever), I don't get even discussing it.
