The OSU ground game churned up 236 yards, and Vernand Morency gained 165 yards on the ground. But 58 of them were on one play on OSU's opening series.
Linebacker Akarika Dawn stopped on the play initially because he thought OSU had moved prior to the snap, and Morency beat Washington to the corner and was off to the races.
It was only the beginning of a day marred by mental miscues on CU's side of the ball.
Colorado failed to take advantage of an Oklahoma State turnover in the first quarter. OSU quarterback Donovan Woods threw one up for grabs that CU cornerback Lorenzo Sims came down with, giving the Buffs the ball at their own 22. CU drove to OSU's 24. Facing third and 5, Klatt hit Ron Monteilh for a four-yard gain. CU opted to go for a first down, but Klatt's throw to tight end Joe Klopfenstein was off target and Oklahoma State took over on downs.
Meanwhile, the Cowboys made the most of a CU turnover in the second quarter. CU freshman Hugh Charles ran into his teammate Stephone Robinson as Robinson awaited a punted ball. The ball hit Charles and OSU recovered the fumble at CU's 11. After a CU defensive offsides penalty, Morency ran six yards for the touchdown, giving OSU a 14-0 lead.
Things turned worse after that. OSU took over on downs with 1:20 remaining in the first half. Five plays later, true freshman Prentiss Elliot beat Sims deep on a second and 1, and Woods put enough air under the ball to give Elliot a touchdown pass. The 58-yard strike came as time ran out in the second quarter, and the point after gave the Cowboys a commanding 21-0 halftime lead.
But the Buffs gave up three more touchdowns in the second half, and were never really in the game after OSU went up 28-0 on a Donovan Woods to Luke Frazier touchdown pass with 1:33 remaining in the third.
CU failed to convert two fourth-and-short plays on the day, and were penalized nine times for 60 yards, including a running into the punter penalty which kept an OSU drive alive. OSU scored later on the series.
Lawrence Vickers was a bright spot for CU's offense, accounting for 168 yards (78 rushing/96 receiving). Sophomore Blake Mackey also played his best game to date, hauling in six catches for 129 yards.
