1) duncan was only a PF when he played with David Robinson. I classify him as a center because of his defense, he plays center defensively, power forwards tend to roam more from around the basket, and are generally quick enough to guard PF's. Tim Duncan needs big help to guard amare, or david west, his feet arent fast enough to D up those guys one-on-one from the elbow. Just watch the highlights, enough said. As a center Duncan is still one of the best, perhaps the most versatile offensive center ever. Calling him a PF gets him a starting nod on the all star game every year(no shaq or yao to contend with) and consideration as the greatest (PF) of all time. Anybody who thinks oberto is an NBA center, is kidding themselves. He cant guard ANY competent NBA center.
2) Tim Duncan has had a much better career as a player than amare stoudemire, not even close.
I am not suprised by the poll, after all fan polls are what they are. Amare is an outstanding talent with alot of work to do to be considered an all time great anything.
