Now that I am thinking about it, it was the same thing at Bristol. We had a lead, and I think with about 8 minutes left, we were snapping the ball with 15 seconds left consistently. At that point we were up 17 points, and the game wasn't out of reach (see Ole Miss vs Alabama). Do that 3 times, and that's 45 seconds you "lost". 45 seconds = about 10% of the remaining clock at that point, which is a big percentage of time you could have wasted.
