He spent much of his first two seasons in Norman as a hybrid safety/linebacker, where he often began plays close to the line of scrimmage.
Jefferson moved to free safety during the offseason, but he isn't exclusively deep; before many snaps he's had in 2012, he's crept closer to the line and has darted in to tackle opposing running backs.
Kansas State has averaged more than 250 rushing yards per game and is led by senior quarterback Collin Klein, who scored 27 scores on the ground last season.
“An offense like theirs, where they run the ball and just smash-smash-smash-smash, it wears you down a little bit,” said OU senior defensive end R.J. Washington. “It's important for us to make plays when you can make them. It's important to do our jobs.”
Jefferson's clean bill of health should make that a little easier.
As for Brown, it seems safe to assume he'll be good to go Saturday; after the North Texas game, Wildcats defensive tackle Javonta Boyd said of the All-Big 12 linebacker, “He's a warrior. If he's got one leg, he'll be out there.”
KSU will certainly need Brown, who led the team with 101 tackles, including 9.5 for loss, and added two sacks and an interception last season. His presence in the middle of Kansas State's defense will be important if the Wildcats are to slow OU's offense, which averages over 540 yards of total offense and includes dynamic, yet powerful, running back Damien Williams.
“We're going out of the pan and into the fire, so to speak, and that improvement that we had the first couple of weeks has to come back in a hurry,” Snyder said Monday.
