I'll quibble on the point about 2009 Cincinnati. They were an average team themselves (in terms of raw talent) but he navigated an undefeated regular season against peer programs. The fact that he repeated that trick in 2012, I just think those two seasons validate each other. I don't give a shit what that team did in the bowl game vs Florida. No Big East teams belonged on the same field as Florida. There was nothing Kelly could have done, even if he did coach that game.
Strong points on everything else. There's no such thing as "half of an undefeated season". That's just called a winning streak.
