Oklahoma football: Casey Walker didn't know about seven-DB scheme

Like any defensive lineman, his eyes were looking at the Mountaineers' line and their quarterback, Geno Smith. He wasn't really aware of what was going on in the secondary.

That is, until he realized that wide-receiver-turned-running-back Tavon Austin kept running around the field and scoring touchdowns. That's when Walker realized there was no Tom Wort on the field.

"I didn't know anything about it until I was on the field and I didn't see Tom," Walker said "I did not know that there were no linebackers out there. It kind of surprised me."

What shocked him even more were the 572 all-purpose yards Austin compiled in the game.

“I had to give them props,” Walker said. “I tweeted at them after the game to tell them what respect I have for them.”

As for that seven-defensive-back scheme, it led to 20 missed tackles — a number that Oklahoma coach Bob Stoops said the defense hasn't come near in a long time.

So, will Sooner fans be seeing Wort and Corey Nelson this weekend at linebacker or will there be seven DBs to defend Oklahoma State's star running back Joseph Randle?

“Uh, I don't know,” Oklahoma defensive coordinator Mike Stoops said Monday. “That didn't work so good.”

STILLS: JEFFERSON TWEETED APOLOGY BECAUSE HE CARES WHAT FANS THINK

Following Oklahoma's 50-49 win at West Virginia, junior safety Tony Jefferson tweeted an apology to fans for the defense's performance, and for his individual play.

Receiver Kenny Stills is close friends with Jefferson, and said the tweet was sincere.

“He was disappointed in the way he played individually,” Stills said. “You've got to understand, if you have 15,000 followers or whatever he has and all of them are saying, ‘You (stink)', he wants to apologize and say, ‘I expect better from myself also.'”
