Would the suns have beat the spurs without the shaq/marion trade?

Personally I think so. In today's game, the hack-a-shack put shaq on the line where he shot 9/20 - probably losing it for the suns. The first two games and this one these teams played were really close, and just the few points lost from the hack-a-shack would've made a difference. Not to mention that Shaq can't dominate the paint anymore, and he slows down the team. I think if the suns still had Marion before the trade, they wouldve won this series [or atleast took it 7 games]. Opinions?
