It wasn't just offensive mistakes; Alabama's special teams cost them in a major way in a two-point loss to Oklahoma.
Ty Simpson's two turnovers were undoubtedly costly. He threw a pick-six in the first quarter and then lost a fumble late in the third quarter with Alabama leading by one, which allowed Oklahoma to take the lead with a field goal.
Those mistakes will be discussed ad nauseam. But Alabama's special teams were an abject disaster in Tuscaloosa on Saturday afternoon, and directly contributed to the home loss to the Sooners, every bit as much as Simpson's miscues.
