Sure and if they got the TD and 2pt conversion there they'd have tied the game and still could have got the ball back. Going for the FG there was just stupid. If they failed to get it it would have pinned the Steelers deep in their own territory and they could have gotten the ball back and STILL been able to tie the game with a TD+2pt. It was 4th and 4 from the 8 yard line, it isn't like they were at the 40.
