Defensive line: B-
The OU defensive line has played well at times, and poorly at others. Senior David King switched between playing end and tackle with some success, and after he returned from his mysterious two-game absence to start the season, tackle Casey Walker played well.
The senior-dominated group loses every major contributor from this season except sophomore Chuka Ndulue.
Sophomore Geneo Grissom, who switched to tight end last summer but returned to defense, saw increased playing time at the end of the season.
In new defensive coordinator Mike Stoops' system, linebackers weren't relied upon as playmakers like they were under Brent Venables. As the season progressed, Stoops tinkered with six- and seven-defensive back units against spread offenses like Baylor, West Virginia and Oklahoma State, with little success.
Earlier in the season, though, juniors Tom Wort and Corey Nelson often struggled and were inconsistent. Freshman Frank Shannon emerged as a strong option in pass coverage.
The secondary was the OU defense's strongest unit for much of the season.
Safety Tony Jefferson and cornerback Aaron Colvin emerged as the defense's top overall players, but even they struggled in shootout wins over Baylor, West Virginia and Oklahoma State.
Senior safety Javon Harris had a strong season overall, despite the overall unit's late-season lapses. He led the Sooners with five interceptions.
Gabe Lynn and Julian Wilson each saw lots of playing time in nickel and dime packages, and showed flashes of their potential. Wilson was there with Jefferson to break up a fourth-down pass in the end zone that sealed the Sooners' regular-season finale win at TCU.
