Having watched Beasley and Griffin to the point of nauseum, I must say the the only thing similar about their game was the results. They both scored and rebounded with ease in college. Thats where it ended. Beasley's game reminded me more of a SF's game and thats what I projected him to eventually be. He played a lot on the outside, but was good at going to the basket and following shots for rebounds.
Griffin is a low post player. Almost all of his points in college came from under the basket. He relies on quickness and strength combined with great leaping ability to most of his scoring. He seldom took an outside shot, a part of his game he needs to improve upon. If I had to choose between the two, I would take Griffin because of his toughness, plus he's bigger than Beasley, and will be playing his natural position. I think Beasley is still more of work in progress. Particularly as to where his natural position is. He's very talented, and will be a very good player, once he figures out who he is as a player. I wouldn't call him a great player just yet....
