Worthy was a jump-shooter SF who had nice post-up moves as well. He wasn't a low-post scorer.
BTW, Worthy was a FAR better low-post scorer than Amare. Worthy had a devastating turnaround jumper, a great up and under move, and the aforementioned ultra-quick spin move that left defenders looking like they were wearing lead shoes. Amare is not a dominant post presence. He is a face-up scorer who can put the ball on the floor and run the pick and roll as well as any big who's ever played. He certainly has the tools to develop that aspect of his game, but he is not yet a great post-up scorer.
