"You know what, it's like he's been here for a couple years," Nebraska head coach Bo Pelini told reporters on Saturday. "He's done a great job. I think he understands what we're doing. I think we're communicating and working well."
Despite less than two months on the job, Warren has picked up the defensive system well according to Pelini.
"For a guy who's been in this system for only five days it's hard to tell. You'd never know it."
On Monday, the Nebraska athletic department released a video feature on the newest member of the Husker coaching staff.
