Even though Smart was limited to just two points in the second half, several other Cowboys picked up the slack for Travis Ford's squad. Senior sharpshooting guard Markel Brown was proficient from downtown, connecting on 5-of-6 three-pointers and finishing with 25 points, seven assists, eight rebounds and three blocks.
Forwards Le'Bryan Nash and Brian Williams combined for 28 points in the front court for the Cowboys. The Cowboys shot 50% for the game and over 50% from three-point range.
The Bulls committed 16 turnovers to Oklahoma State's nine on the night and shot just 39% from the field, while connecting on just 5-of-18 three-pointers.
Freshman center John Egbunu displayed his potential and skill against the Cowboys, finishing with 15 points on 5-of-7 shooting, eight rebounds and two blocks.
