SAN DIEGO — Oklahoma State defensive coaches talk a lot about “chunk plays” — those big yardage gains that not only move the ball up the field for the Cowboys' opponent but also take the wind out of OSU's sail. Oregon beat Oklahoma State in the Holiday Bowl Tuesday night because the Ducks got chunk after chunk, finishing with five offensive plays of 40 or more yards. OSU managed to recover after giving up a couple of the big plays early. Oregon got its first “chunk” on the opening play, with quarterback Jeremiah Masoli completing a 47-yard pass to Jamere Holland on a trick play. OSU ended up holding the Ducks on that drive. “We didn't do a good job of staying with our responsibilities,” said OSU assistant Joe DeForest, who co-coordinated the defense for the bowl game. “I think our kids did a great job, when they hit a big play on us they came back and fought and we held them. And then they hit a big play. Those are things on defense that you just have to eliminate.” On the very first play of Oregon's next possession, Jeremiah Johnson got an even bigger “chunk,” running 76 yards into the end zone. OSU had to recover again after Oregon had a 50-yard pass play to start a drive in the second quarter. The Cowboys blocked an Oregon field goal attempt to end that possession. But the chunks piled up in the second half and the Cowboys couldn't stop the bleeding. Oregon put the game away with a borderline-chunk play, when LeGarrette Blount ran 29 yards for the touchdown to put the Ducks up 42-31. “Early on in the game they started off doing a lot of trick plays and everyone was just, ‘Play your position, play your role,'” OSU linebacker Pat Lavine said. “We did that in the first half. In the second half people started playing other people's jobs and things went downhill from there.” The big plays weren’t just on defense, though head coach Mike Gundy said afterward, alluding to the Ducks 33.5 yard average kick return. “We gave up a couple big plays in special teams and we're not accustomed to doing that,” OSU coach Mike Gundy said.
