I think the thought is that if Heupel doesn't win with this team with what he considers a Heisman candidate match made in heaven QB, say he wins 10 games, then that's his ceiling.
While yes its dumb to fire after winning 10 games but I don't disagree that an "eh" season probably means we've seen his ceiling.
He also made the point that recruits will bolt if they don't win big. He's that high on him, higher than just about anyone I've heard. I'm trending that way myself. Should be a great year but I am expecting rookie mistakes to likely cost the biggest games.
