I'd hate to see Bosh go to Houston. Another team that will misuse him.
Bosh needs to play with an inside-outside threat or solely a perimeter threat but not someone who is solely an interior player like Dwight Howard is. Bosh will not have a large impact in Houston because Bosh and Dwight are not good for one another. Still, a good addition who will improve their team but not the star level impact Houston will be hoping for.
Who would be a good compliment to Bosh?
Power forwards. Bosh works very well as C alongside almost all PFs. The ones with more quickness and skill the better.
If must have a center alongside Bosh, then an inside-outside one like Marc Gasol or Tim Duncan. Or a PF/C like Garnett, Pau Gasol, Aldridge. Lesser option again is a more limited scorer but good high post passer like Joakim Noah.
Worst options are ones that hang around in the paint all game long and turn Bosh strictly into a jump-shooter (as he has become over last few years in Miami). Also troubling are slow footed players that decrease team speed but that isn't an issue with Dwight. Say a Roy Hibbert type.
