Middle of the pack starting PG is not a team's biggest weakness. Especially when you have T-Mac, Yao and Artest. Rocket's biggest weakness besides health is depth/size at the 4/5. They ahve a bunch of undersized PF and no good back up C. Heat: depth, health, PG and C... We wouldn't even be in the NBA if it wasn't for Wade... Raps: Slashing wing and Andrea Bargnani's shitty development.
Celtics: Age, a lot of wildcards in the reserve roles, especially at the wings Kings: No glaring weakness, IMO, but no noticable strength either. We could use tougher guys at center.
Blazers: Preseason has looked a little like an episode of M*A*S*H*, so I think injuries/staying healthy seem to be a pretty big weakness.
Knicks: defense, offense, chemistry, turnovers, consistent shooting, effort, over salary cap, center position
