Every argument about how limited the offense was makes the decision less defensible, not more. Score from the 2.5 yard line. Or score from your own 20.

During the game day thread no one got exercised because as fans it was stunning to get the game tied. Everyone was happy the team still had a shot in a game that they were outplayed for large stretches (Defense was magnificent except for OT). That is not the coaches job, to be impressed with a tie game. The coaches job is to win. And the 2 point conversion was the best opportunity.
