Marion is without question a better player than Diaw and a more important player to the Suns. The Suns can find a nother guy who is versatile like Diaw, but what Marion does for the suns, noone on his entire teams really tries to do. He rebounds and plays defense. In case u havent noticed, that is very rare on the Suns roster. Marion is more vital to the Suns winning a championship. Who cares about Diaw's ability to score? Everyone on the whole team can score except for Brian Grant. They need Marion's prowess on th boards, and his defensive intensity.
