Roberson leads Colorado past Utah 55-48
The win was the second this season over the Utes, who lost 73-33 to the Buffaloes (17-8, 9-4 Pac-12) on New Year's Eve in the Pac-12 debut for both teams.
Colorado guard Carlon Brown suffered through a miserable shooting performance - going 2 for 12 - and finished with five points in his return to Salt Lake City, where he played three seasons for Utah.
The Utes trailed by as many as nine points in the second half, but tied the score at 44 with 4:23 remaining. Colorado then went on a 6-0 run, Dufault got a late block and the Buffs sank key free throws down the stretch to secure the win.
