In 2012, in SEC games and the bowl game, we scored 12.66 points per game in the second half. The best second half performances came against Auburn (21), UT (14), and Ark (28). We only managed one TD in the second half against UK, Bama, LSU, and OM. We did score 13 second half points against aTm and 10 against Northwestern.
You can extrapolate whatever the hell you want from these figures, but Auburn, UT, and Ark all fired coaches at the end of the season.
