Here's a mildly exciting quote from Washburns blog post on Willis's commitment. (The quote is from Bullitt coach Troy Bar.)
"The No. 1 thing he has is the ability to create mismatches. He needs to develop his inside game, but we're talking about a kid who is 15, wears a size 18 shoe and has a 7-1 wingspan. The amazing thing is that he really hasn't had that one growth spurt yet."
