Humphries and Jawai are strictly power forwards, who couldn't function at the center position any better than Dirk could. Dampier is a true center who is an above average defender in the league. Having Gortat as his backup is perfect. Marion at the power forward spot isn't a problem, but Dirk at center would be disastrous. He functions at an elite level where he is right now, as a power forward. His game would be entirely different if he played center. If this trade ends up going down, the Mavs will have to deal with two legitimate sixth men. PG: Kidd SG: Redd SF: Marion PF: Dirk C: Damp Sixth Men: Terry, Howard Balancing out minutes is going to be very tough for the team as well as frustrating to Redd, Terry, Marion, and Howard.
