The problem with the original post is that you act as if no mid-major has ever upset or out-played a team from a bigger conference.
Single-game upsets and near upsets happen all the time. EVERY coach and every team has lost or nearly lost a game that on paper they shouldn't have. Don't judge ANY coach by ONE game, because by that standard no one is qualified to coach a big time program, and we will all be doing chores on Saturday rather than watching college football.
Now, if a few seasons down the road the Vols are consistently playing like they did this past Saturday, we can say we have a problem. But I'm not going to say that after four games into a coach's tenure--especially a coach who inherited the stink-pile Dooley did.
