Never been a true, lone defensive coordinator. He's been a co-defensive coordinator at a couple of stops, but you know how that "co" title goes. A lot of times that title is just given to a coach to make them happy/get them more money. So there's some concern there. However he's supposedly a great recruiter and a high energy guy. Also, I'm just going to say it, it never hurts to diversify your staff even more to attract recruits.
