Stock answers, but they're accurate:
East: Hawks. They need to get a third dog to really be a powerhouse, but nonetheless they should be performing better than they have so far. Perhaps they need to embrace balanced and have Deng be the 3rd guy and embrace him. I realize they started in balanced and switched to outside, but it's not working out to this point.
West: Rockets. They'll be fine for the playoffs, but right now they are underperforming. Kobe is the trump card above all trump cards, and Dwight is the perfect FBB center, so I think that they'll figure it out.
I think Wade is probably the stock answer here as well, but I'll go off the board with a homer pick of Richard Hamilton (he's expiring so I can't really be too much of a homer pick here). His defense is very underrated because he never gets lit up in boxes and he can play both the 2 and the 3 effectively. Deadeye shooter that produces high volume as the 3rd option. Really nice third dog for a team.
