Some schools fan bases have a tradition of sticking it out until the end, no matter what. I would have bet money that the Arkansas fan base was one of those, until this game. It wasn't the fact there were 3 to 5% (yep, that's about what it was) of the seats filled at the end of the game, it was that the mass migration out of the stadium began at half time. Half-time. By the middle of the third quarter, less than half of the fans were still there. That's astounding, in the third quarter, less than HALF. No doubt the issue was decided by then, but you're on the sidelines as a player, and you can not only see the stands empty, you can feel the stands empty, hear the fans breaking camp and BS'ing on the way out.
Emotion is part of the game. Much harder for the players to get back on the field, and I mean MUCH harder, when that is happening. It was just a wierd sight at an SEC game.
