The Rockets have officially signed Pops Mensah-Bonsu. That gives us Pops, Scola, Landry, Hayes, Cook, Dorsey, who are all interchangeable at their position. Who's expendable/tradeable? Who would we trade for? I can see Cook as expendable, but not tradeable, and as much as i love Chuck Hayes' game, we really need more size with the absence of Yao. Dorsey has come a long way, but still has a long way to go. So with all this depth at the position, who stays who goes and who gets minutes? Comments?
