Steve Francis wasn't in the league at 20. Nor at 21. He had 2 years in JUCO plus the 1 year in Div 1. I think you are understimating Rose.
Rose definitely has a great game for such a young guy and is already a solid pro. Can't wait to see him develop even more of his game, like an outside shot and to better control the flow of things. He's going to be one of the truly special players.
In fairness, Steve Francis looked like a potentially dominating talent as a rookie. He was really freaking good before all the weird health issues, fatness, bad attitude and major injuries.
