I thought about this during the game, and while I do not believe that he thought this deeply, there is a level of logic in letting this guy kick the field goal. They were down by 7, knowing that they needed a TD and an Extra Point to tie, the kicker had the potential of being on the field to tie the score at the end of the game to send it to OT. Even if he missed the field goal, there was a chance that they could still score a TD and you would need the kicker to tie it up. Maybe he wanted to let him "get right" on a FG, instead of on the necessary extra point. I dunno. Just a thought.
