the best defensive rating on the team, he can handle the ball, he can jump out of the gym, he's a decent passer, he plays an unselfish brand of basketball, he's got a great basketball frame, and perhaps most importantly, he seems to have the work ethic and desire to improve his game. His advanced stats (DRating (#1), Win Shares, Rebound % (#1), BPM) are some of the best on the team as well - which is incredible for a kid who seemed as raw as he was coming in.
In short, he's exactly what modern NBA teams are looking for - pieces that can handle the ball, defend multiple positions, and make 3s. I think we'll be lucky to have him beyond next season. Ideally he holds off on declaring until after his Junior year.
