You can make sure the players aren't so out of it emotionally that they do dumb things. How many times have you watched a rivalry game when BYU does something completely out of character that they haven't done all year long? I can think of plenty. How many times has BYU gone into the game favored and lost because they played uncharacteristically bad.

Things happen, Jake will have a pick or two that he shouldn't, but no "running backwards, put the ball down to steady yourself, fumble it backwards" Jake Heaps specials.
