What's the point of beating your rival when the other team ends up in the playoffs anyway? OSU's loss literally made no difference. They likely would have lost again to Oregon anyway. If GT would have beaten Georgia, then Georgia would still be in the Big 12 title game. There are of course going to be situations when beating your rival knocks them from the playoffs, but only if they are fringe anyway. More often it will knock an ACC or Big 12 team from contention, and not SEC or BIG teams.
