I think that's way too much of a stretch. He was good last year, really good. But that's it. No way did that one season vault him into one of the all-time great college basketball point guards. I'll just give you one example, though I know many here could give more: Oscar Robertson's three-year career at Cincy: 33.8 points, 15.2 rebounds, 7.1 assists.
I know you're not comparing him to the Big O. I just don't want people people thinking that what Wall did was all-time. Wall's numbers by the way: 16.6 points, 6.5 assists and 4.3 rebounds.
