I wasn't basing my opinion of Wall on statistics, and I probably should have said I think he is the best point guard prospect in the last 30 years, and not the best point guard. On performance, I really don't know who would be the best over that period of time. I would take Wall over Rose as well. Again, not saying he played in college as well as Rose, just that he is a better prospect.
I have never seen anyone as fast with the ball as Wall. He is fearless, unselfish, works hard and smart. He certainly has things to work on (shooting for one). But, I will be absolutely shocked if he isn't the best point in the NBA for most of his career. As lazy as everyone is in the NBA, I just can't see anyone staying with him in the open court I guess I see him as Jason Kidd in his prime only 25 times faster.
Your points are well taken though, his performance to date wouldn't support my opinions to date. Obviously, this is just a subjective belief and opinion of mine.
By the way, I see Monroe and Dom Jones as the sleepers in this class.
