DALLAS — So much for the idea that Oklahoma State didn't care about playing in the Heart of Dallas Bowl.
Clint Chelf threw three of his team's five touchdown passes and the Cowboys shook off a tough Big 12 finish by rolling up 524 yards and forcing five Purdue turnovers in a dominating 58-14 victory on Tuesday.
Oklahoma State coach Mike Gundy didn't hide the disappointment of sliding down the bowl priority list with an overtime loss to Oklahoma when the rival Sooners scored in the final seconds of regulation, followed by another narrow defeat at Baylor to finish the regular season.
The Cowboys (8-5), a year removed from finishing the best season in school history with a win in the Fiesta Bowl, sure didn't seem to lack motivation. They put together the biggest bowl win for Oklahoma State since Gundy was the quarterback in a 62-14 rout of Wyoming in the 1988 Holiday Bowl.
Some of the seniors, those guys, would like to have been in a better bowl, said Chelf, who was 17 of 22 for 197 yards with no interceptions. We're a highly motivated group. I think everybody wanted to go out there and prove people wrong, show them we could win a game like this.
Robert Marve didn't get to 100 yards passing until Oklahoma State led 45-0 as the Boilermakers fell to 0-4 on New Year's Day.
The Boilermakers (6-7) gave the Cowboys short fields on their first two scores after a long punt return from Josh Stewart and the first of Marve's two interceptions. Various mistakes with the game still close in the first half — a missed field goal, a drop with a receiver behind the defense, and failing to hold on to an easy interception — ended any hope for Purdue.
