By my count, we are 7-0 against the Big Sky conference in the playoffs. As Ed noted, they have a hard time matching up to our style of play. With so many of their teams just flinging endless passes during a game, their defensive fronts must be built to rush the passer. They are quick but rather light by our standards and virtually helpless against a midwestern power running attack.
Let us not forget one vital contribution that should not be overlooked. Justin Spencer fell on that fumble in the red zone in the fourth quarter. We lose that ball, there would be no last second heroics.
