When the Bo Pelini era started, I remember Beck as the last coach to join us. That didn't happen until January.
Bo remaining on staff at LSU had to have impacted a lot of timelines - things that aren't applicable to this scenario.
It's probably not the end of the world if this drags on though, maybe it's even a good thing. I could see Orgeron wanting to slow play things to see how the coaching changes open things up for him as an HC. I'm sure he'd be a candidate for plenty of teams after his success at USC last year. He might not be available to us until late December when things have finally started to work themselves out at places like Michigan, Florida, OSU, etc.
