I'm not sure where you got that story from...but, it's not accurate. I heard Coach say he felt the game was well in hand up until about four minutes left in that game. In fact, I recall his statement being along the lines of "it goes to show how fragile a season can be" when he was commenting on the fumble when we were up 12-3.
If he were going to bench someone who had a bad game that day it would have been Ingram. After all, it was his fumble that allowed UT to make it 12-10.
