Speculation here (granted, the source seems to have as much info as any of us do) that Segrest could be next.
Taking it at face value, though. We have our man at A-State. Greenlaw's dad, Brian Early. Can pay him a fair but very modest salary to save money for new DC. Former FHS DC and admin asst for CBB before A-State gig. This guy studies film better than anyone I have ever seen; the ultimate schemer. Big believer in tailoring scheme to maximize your players' talent. Had one of the best DLines in CFB this year. They had like 15 TFL's in their bowl. Crazy. Anyway, I don't see it getting worse - and at least we would be saving money but with more upside. Recruits well too.
(Note: Hijacked another thread with these stats a couple months ago, but thought I would share again since some may have missed and now may become more relevant)
