For me both players are great but i think that Phoenix Suns will get more out of Shaq than Marion. As you can see their line up, all they needed was a strong and dominant center who can contribute on both defensive and offensive ends. For some guys who don't know this, Amare is a power forward so with a Shaq and an Amare tandem, their team will be a lot more better than Amare and Marion before. Plus with the passing skills of my idol Steve Nash, damn! The Phoenix Suns would probably own in the playoffs.
