He's cooked if we go 6-6, IMO. Even with a first-year AD. I'm not sure anybody knows the precise effect working under a first-year AD has on Butch's job security. I understand the argument that it increases it, but I also understand an equally-believable argument that it decreases it.
Put some meat around what 6-6 would entail - who exactly would those losses be to? That's a lot of losses; we'd have to lose to multiple inferior teams to accumulate that many this year.
Florida, Georgia, Alabama, and LSU are 4 likely ones. Georgia Tech would likely be another. Take your pick from among South Carolina, Kentucky, Mizzou, or Vandy for another. If there's a loss to Indiana St, UMass, or Southern Miss, all bets are off. Don't think many people would tolerate that.
