There's a lot of interest about how good Peter Sirmon's defense will be in year one. Let's look back at some of Dan Mullen's other defenses for comparison's sake.
Dan Mullen has had a lot of defensive coordinators. And we've seen several different approaches to defenses from each of these different coordinators. But all of those approaches have come under a 4-3 scheme.
Peter Sirmon is doing a complete overhaul, more or less, and is changing things up to a 3-4 scheme. It makes sense. Mississippi State has quite a few talented linebackers on this team and there's some questions about how the defensive line will play with the loss of Chris Jones.
