I could see the Lakers earning a #1 seed. The combo of Kobe, Pau, Bynum, Odom would probably be too talented to vote against, even with Bynum's health problems.
I think the Heat would be a lock for the #1 seed in the East. Sure, Chalmers/Arroyo is thin in the back court, and people would scoff at Big Z / Anthony in the front court, but a team with two top-five picks and another first rounder isn't going to finish lower than 1st in its conference.
The Celtics, I think, would probably be #2 in the East. As the CrotoNats proved last year, depth wins, and the Celtics would have probably the deepest top-tier team in the league.
I wouldn't be as sold on teams like the Magic or Mavs earning a top seed in the CB-NBA, though. I think people could point to a lot of roster flaws, and they'd fixate on them.
