1. 2011-Jake Heaps gives Utah a touchdown by leaving the ball for a defender in the endzone. Not how you want to start your game.
2. 2012- Riley Nelson missing open Hoffman at Notre Dame. Probably wins that game for you.
But the most painful...
3. 2004- Matt Payne chip shot field goal to end Boise longest winning streak in the nation. And..he misses.
Any other ones come to mind?
