Why go for 1 late in the 3rd quarter when you're down 2?
Especially if you're already going to eschew 3 points and go for 4th downs earlier in the game.
Why go for 1 point when you can get 2 and tie it? I understand maybe if it's early in the 3rd quarter, but not when there's only about a quarter of the game left. Usually I prefer not to chase points by going for 2 all the time, but in a situation when you're actually down 2 and the game is winding down, I don't see much of a difference being down 1 or down 2 (if you don't get the 2-pt conversion).
