Buried in this extensive listing of the most valuable players in the NBA by Bill Simmons, is a little muse about NBA stars playing soccer, which I will reproduce here in its entirety so you don't have to go searching for it:
By the way, I've been watching the World Cup for four weeks trying to decide which NBA players could have been dominant soccer players, eventually coming to three conclusions. First, Allen Iverson would have been the greatest soccer player ever -- better than Pele, better than Ronaldo, better than everyone. I think this is indisputable, actually. Second, it's a shame that someone like Chris Andersen couldn't have been pushed toward soccer, because he would have been absolutely unstoppable soaring above the middle of the pack on corner kicks. And third, can you imagine anyone being a better goalie than Shawn Marion? It would be like having a 6-foot-9 human octopus in the net. How could anyone score on him? He'd have every inch of the goal covered. Just as a sports experiment, couldn't we have someone teach Marion the rudimentary aspects of playing goal, then throw him in a couple of MLS games? Like you would turn the channel if this happened?
