I'm sure it's already posted and I agree with only giving college performance so much when trying to estimate a professional career, but, the game against Vanderbilt, which I watched the end of last January was quite a show.
Williams hit 22 of 22 from the line and 43 points. A pile of those field goals were layups, he didn't shoot many threes in college.
With his size in the NBA, he's really a winger with a low center gravity.
In college he ran the offense a good deal of the time. Perfect guy for Stevens if he can hit some threes.
