Time to pass out a few helmet stickers to put a cap on a set of games that proved to be interesting. Plenty of this week's "What to watch" came into play all day on Saturday.
Iowa State defense: No sense in picking out one player on a defense that pitched a shutout against Northern Iowa in a 27-0 win. The defense scored two touchdowns to the offense's one, and forced five turnovers. This one was never in doubt, and the defense was the reason why. Jeremy Reeves (94 yards) and A.J. Klein (25 yards) returned interceptions for scores. Any more credit goes to coordinator Wally Burnham.
Carson Coffman, QB, Kansas State: If you're the difference in a close win, you're going to earn a helmet sticker. Carson Coffman, that means you. The maligned senior quarterback spearheaded a lengthy 13-play, 67-yard drive capped by his go-ahead, 7-yard rushing touchdown in the final minute of Kansas State's 17-13 win over Central Florida. Coffman completed a pair of third-down passes, including an 18-yarder on 3rd-and-10 to keep the drive alive. The win means the Wildcats are 4-0 for the first time since 2003.
Jonathan Nelson, DB, Oklahoma: Did you think I was kidding? Oklahoma managed a tight road win, and Nelson was the difference. He chased down Cincinnati receiver D.J. Woods on a 73-yard catch-and-run, and poked the ball out and into the end zone, where the Sooners recovered for a touchback in the second quarter of their 31-29 win over Cincinnati. Later in the second quarter, he intercepted a pass in the end zone for another touchback. A missed extra point kept the Bearcats from being able to go for the tie in the fourth quarter, but without Nelson's plays, the Sooners would be 3-1 right now.
Robert Griffin, QB, Baylor: Griffin wanted plenty of his throws back from last week's loss to TCU, but he took advantage of the ones he got against Rice. Griffin tossed two touchdowns longer than 40 yards and added another short one in Baylor's 30-13 win over Rice. He completed 20 of 28 passes for 268 yards and ran for 50 yards on 11 carries.
Lavonte David, LB, Nebraska: Bo Pelini wasn't exactly singing his praises ("He has a lot to fix. It goes well beyond statistics.") after the game, and David downplayed his effort, saying it "doesn't feel like it," but the first-year starter racked up 19 tackles against South Dakota State in Nebraska's 17-3 win. That's the most of any Nebraska linebacker since Barrett Ruud in 2004. David also broke up two passes.
Honorable mention: Kansas' D.J. Beshears, who scored three touchdowns, including a 96-yard kick return in Kansas' 42-16 win over New Mexico State.
