"We need to get more out of him than we did (Saturday)," Holgorsen said. "I think he played 12 snaps, but we've got to use him in nickel situations. How many times did William & Mary come out with three or four receivers? Five, six, seven times the whole game?
"Obviously, that's what Oklahoma likes to do and their three- and four-receiver sets are going to mean more time and a lot more opportunities to get in the game and show what he's got."
Dillon can cover receivers in the defensive backfield and blitz or play the run off the edge. He can start away from the line of scrimmage or on top of it.
"They feel as though I'm a good body for that position," said the 6-foot-1, 200-pound Dillon, who before last week hadn't blitzed in a game since he was a senior in 2011. "All we're doing is trying to find the best 11 guys who can play ball, no matter where you play. If you're one of the 11 best, they'll find a way for you to be on the field."
Where Joseph's position sometimes keeps him deep, Cook's throws him into the action. Again and again last week, even against William & Mary's conservative fronts that protected the passer with seven blockers, the aggressive, instinctual Cook threatened to come off the edge.
That will change against the Sooners because they'll spread their offense out more. The Tribe played so compact that Cook was safe to crowd the line of scrimmage. He said he was never ordered to blitz and instead just chased the ball when he happened to find himself in the backfield.
The Sooners are bending their reputation of a passing team, though, in order to protect and nurture redshirt freshman quarterback Trevor Knight, but also to make the most of an enormous offensive line and a line of quality running backs, led by Damien Williams and Brennan Clay and often facilitated by versatile fullback Trey Millard.
The Mountaineers figure to use fewer 3-4 and 4-3 formations this week than they did last week in the normal course of play, which means more Dillon to combat the pass, but also more Cook to slice in and contest the run or sometimes blitz, which he says is built into the scheme.
Cook said he blitzed three times last season, though he turned one into a forced fumble and a Doug Rigg touchdown return against Maryland. Patterson will call Cook's number from time to time and Cook said he and Joseph are "free to freelance" to disguise their intent before the snap.
"They're using me just like in 2011 when (former defensive coordinator Jeff) Casteel was here," Cook said, harkening back to the 3-3-5 that isn't much different than Patterson's nickel or, of course, his 3-3-5. "It's very similar to that. I played defensive end in high school and (Patterson) knew that. He just wanted to incorporate that into this defense."
His leg healed and his mindset calibrated, Cook said he's healthier than any time since he stepped on campus in 2009 and has never been more excited to play than he is right now.
"It feels good," he said, "to feel good again."
