re: Did Marcell Dareus single-handedly destroy football program?

No. There was zero chance they win that game, even with Colt. The horns weren't stopping Bama. And Bama let off the gas, so it became a closer game. As soon as they blitzed they caused severe turnovers.

Marcel Dareus' hit on Colt did provide an excuse. And Mack Brown ran with that excuse. So I will say that the loss killed Mack Brown as a coach.
