re: How long can we realistically keep this current coaching staff intact?

One of the great things about this staff is that there are several key "career coordinators". Chief is in the position that he is comfortable with and I've heard in interviews (way back, no link) that he does not aspire to be a HC. Now that Stud is OC, I don't see him leaving either for a while, although it's possible. Due to health issues, I'm guessing Krags actually stays. I don't see him taking on a tougher role, and from what I've seen, LSU has treated him well. I seems to be a good fit for both.

Ron Cooper is one that I would hate to lose, but oddly enough, I haven't heard his name mentioned for any openings. Frank Wilson will probably leave for a larger role at a smaller school at some point, hopefully not soon. I would be shocked if BG is here for more than another season.
