I'll preface my rankings with this caveat: I'm assuming that there will be no catastrophic injuries to any team. However, every team has the very real potential to lose a player to injury, and with it, the very real chance to finish as a lottery team.
1. New York Knicks: best player in the division in Wade, and a nice supporting cast around him. Would prefer some veterans on the wings, rather than a collection of first and second year players.
3A. New Jersey Nets: perhaps the best roster, in terms of flexibility. A strong and nicely fitting seven-man rotation (counting Williams and Collison off the bench), covering all positions. Decent frontcourt depth, questions on the wings.
3B. Boston has a great tandem in Bogut and Rondo, and nice complementary players in Landry and the volatile Smith. Some questions about the SF position, however. Is Outlaw a legit starter? Is Kapono still a rotation player? What can Ebanks bring? And is Rush a starter in the league?
3C. Toronto has great talent in the starting lineup, but the questions regarding Perkins' comeback cannot be so easily dismissed. The starters will need to play 40 minutes a night, and due to a lack of depth (why only 11 players?), they'll burn out during the last 20 games of the season.
5. Philadelphia's roster seems to be terribly imbalanced. Three undersized bigs at the backup PF slot, leaving Anderson the only legit C option on the team. Green the only rotation-worthy SF, yet Philly carries two young backup PGs behind Watson. I think this is a lottery team, even as best-case scenario.
