You are out of your mind if you think Derek Willis is working his way into the 1st round of the NBA draft. Willis is playing because Labissiere, Humphries, and Lee couldn't deliver. Calipari had nowhere else to turn, and Willis is taking full advantage of his opportunity. That's the kind of courage and effort we want from our upperclassmen. However, the title of this thread is a fair assessment. While Willis remains a defensive liability and a streaky shooter, the area of obvious improvement is his hard work to win inside rebounding position. I'm not sure that I have ever seen a player make such a large fundamental improvement as a rebounder over a 1 month period of time. It's amazing. It won't translate to the NBA, where big bodies and high level athleticism dominate. But it is making a huge difference for this team at a critical point in our season, and it's good to see. Willis is a 4 year player who will have his hands full with Adebayo, Gabriel, and SKJ next year. Will be interesting to see if Willis can play at this level against Kansas on the road. Big test today for Derek, who can still be exploited on the defensive end by stronger and more athletic bigs.Seriously may be working his way in to a 1st rounder, has all of the tools and is putting it all together right now.
