By Joe MussattoCOLUMBIA, S.C. — Kristian Doolittle's Friday performance in the NCAA Tournament reached a Blake Griffin level of dominance. Doolittle notched a 19-point, 15-rebound and five-assist stat line in Oklahoma's 95-72 win against Ole Miss. He's the first Sooner to post a 15 and 15 game in the NCAA Tournament since Griffin scored 23 points while collecting 16 rebounds against North Carolina in 2009.
