Roberson averaged 10.9 points and 11.2 rebounds per game this season while helping Colorado to 21 wins and a trip to the NCAA tournament. The 6-foot-7 forward projects as a second-round pick. His departure means the Buffaloes will be without their third-leading scorer and top rebounder from this season.
