If it's Frost as the next HC, there is this interview with his DC. Appears he is a multiple front guy.
Q: Where you've been in the past you've run a 3-4 defensive front. Is that what you envision for the UCF defense going forward?
A: "Is there going to three down linemen? Yeah, maybe. Sometimes, sometimes not. The thing I don’t understand – you guys know more about it than I do now – you know, there's a three-technique, a five-technique and a one-technique. This guy's got his hand on the ground and now it's a 4-3. Now he's standing up and it's a 3-4. It's going to be a multiple defense. Sometimes it'll be four guys with their hands down, sometimes three."

Q: So what can you tell the UCF fans what kind of defense it's going to be?
A: "Well, other than what we've already talked about? You know I think in this day and age of the way offensive football is going, the way to win games on defense is sacks plus turnovers minus explosive plays. We want to get the ball back in these guys' hands as much as possible, so we have to be aggressive, we have to take some chances. But the kids are going to have fun. You're going to see a fast brand of football out there where kids are playing hard and trying to get the ball."
