Mixture of luck and good clock management. I cannot tell you how pathetic it looked for Sefo to be playing a game of tag to run out the clock though. A P12 team having to finesse it's way to running out the clock against the worst D1 team in America...totally embarassing.
It was pathetic and small-time. If you won't run the ball three times then you shouldn't be coaching at a P5 school. Small-time loser mentality. Keep fist-pumping.
