re: LSU fans how much time will Coach O get?

It will most likely take until year three to see what sort of impact Orgeron is making on the program. Right now, you're looking at the same coaching staff LSU had last year except Orgeron has replaced Les Miles and Matt Canada has replaced OC Cam Cameron. There should be a lot of continuity, and if Orgeron really does let Canada open up LSU's offense then LSU will look like a Les Miles team that actually gameplans for an opponent's defense.

IMHO the key will be how well Orgeron recruits. Keeping the coordinators will also be important, but that was always the case with Miles, anyway. At least on defense.
