I was just checking out the Draft Express player rankings for this year's NBA draft. They had D'Angelo as the number 4 overall. More interesting is when you rank by class. They rank Shannon Scott as the number 7 senior prospect in the country and have him as a late second round pick potentially. Other notables: Slam as the number 24 senior, Amir as the number 50 senior. Jordan Sibert checked in as the 39th ranked senior.
