I see why you would say that, but man, Ace was playing like the best player in college basketball the last 2-3 months of his senior season. I'm not sure Osby has quite reached that level. And they are doing it a little differently as well. Ace didn't shoot as many 15 footers, but hit more 3's, and was a little better around the rim.
Taj Gray might be a little better comparison for Osby, though their games were different too.
