Nebraska leads the nation in pass defense. Oklahoma State is third nationally in passing. How the Cornhuskers fare against OSU's balanced attack, led by wide receiver Justin Blackmon, is the marquee matchup when the Cowboys host Nebraska Saturday afternoon at Boone Pickens Stadium. "I'm sure they'll bracket coverage Blackmon," OSU coach Mike Gundy said Monday on the Big 12 teleconference. "Our guys have to be prepared and have a plan how to attack that. And we have to protect. They've been able to get pressure. There are some good matchups that should make the game interesting." After watching Blackmon compile 10 receptions for 207 yards, Texas Tech coach Tommy Tuberville said Blackmon is an elite receiver that's difficult to stop, even with double coverage. "He plays fast. He's big. He's physical," Tuberville said. "The only touchdown they made in the second half we went for an interception. We have a safety that jumps pretty good and (Blackmon) just out jumped him, made the reception and ran about 50 yards. "He had a great day on us but we focused on him. It wasn't like we tried to cover the field and tried to be balanced. We put two guys on him. He has so much acceleration. He's a heck of a player... He has no fear. He'll catch it across the middle, post routes, go routes and short routes and breaks tackles. That's the quality of a great receiver." Despite Nebraska's loss to Texas, Gundy said the Cornhuskers are still an elite team. "A week ago, or 10 days ago, most people across the country would think they had a chance to compete for the national championship if they had continued to move on," Gundy said. "College football is so unpredictable. Each week we're all vulnerable. Hopefully our guys understand that." Nebraska coach Bo Pelini said Monday he probably made a mistake when he removed talented freshman quarterback Taylor Martinez in the second half after the Longhorns stuffed the Cornhuskers' option game. Pelini said Martinez will start Saturday in Stillwater. In the loss to Texas, Martinez was held to 21 yards rushing on 13 carries and was 4-of-12 passing for 63 yards. Unhappy that he was benched last week, Martinez still ranks 10th nationally in rushing (126.3 yards per game). "He's very fast and elusive and has great breakaway speed," Gundy said. "You have to do the best you can to contain him. He's going to make some plays. He seems to have a great attitude and wants to compete. It's important to contain him. You have to run to the ball." Gundy was asked if Texas provided the blueprint on how to stop Martinez. "A blueprint? They were the first people to do it is the best way to put it," Gundy said. "Texas used great speed. They rallied to the ball and were able to tackle in space. It's really pretty simple when you watch it. They ran him down and made plays." Since some preseason polls predicted OSU might finish last in the Big 12 South, Gundy was asked if he's surprised by a 6-0 start. "For me to say I wouldn't be surprised at all by the performance we're getting out of some of our younger players would be somewhat misleading," Gundy said. "I felt we had a chance to compete and would have an opportunity to win our games. "But you never really know when you have a new quarterback, four new starters on the offensive line and so many role players on defense that are true freshmen. I don't know if surprised is the best word. But I'm very pleased with the performance we're getting up to this point." Gundy elaborated he and his staff saw talent during fall camp and young players would benefit from watching veterans qualify for bowl games. They hoped younger players would step up when their opportunity arrived but they lacked experience. "I had confidence the young guys would be able to play better at an earlier stage in their career than the last group we had here, the big group of players we had graduate last year," Gundy said. "But there was nothing to say we were for sure. They just had to play."
