It's because I didn't want to listen to all the Ute fan nonsense and camera closeups of them while Utah knelt the game out. I then was about to fire up the Playstation to blow up stuff while I decompressed. At the last second, I decided to check the ESPN Gamecast on my phone to look at a couple of stats when I noticed the game still hadn't ended and that somehow, BYU was on the 50.
So I immediately put the game back on, just in time to see the winning FG.
Close call.
