Overall, I would say the winners were New Jersey (Gerald Wallace is a huge minutes eater and will give them 40 above-average minutes a night) and Houston (shed the horrid end of their bench and acquired a guy in Camby whose rebounding and defense numbers per minute put him in the top 5 players in the entire league.
Nick Young? Good luck, Clips.
The Nugs' dumping of Nene has to be an enormous indictment of their off season judgment that he would become a great center -- but at least if you feel that way you may as well dump him ASAP before no one will take him.
Washington gets rid of Javale McGee and Nick Young - thus increasing their basketball IQ by 5000+ points. They do owe NENE a gazillion dollars (or whatever Brazilian currency he requires payment in).
The Lakers? Sessions is an odd player. He can be very good, or he can be very non-existent. They failed to get Beasley (who I think would have been a great get for them in light of Odom's absence) and I think ultimately that will hurt them. Can they continue to get 40 a night EACH from Kobe and Bynum? If so, then no worries.
