Hilarious. Doesn't matter that it was a great play-call resulting in a wide-open receiver who could have easily scored, the coach is an idiot because they didn't kick it. Okay.
What's hilarious is that you think you are correct on this, when you couldn't be any further from being correct. Langsdorf made a horrendously bad call on the 4th and 1. Great play call? You and I have different definitions of a "great play call." Most great play calls that I've seen have one common theme. They succeed.
Most coaches are thinking that they may have maybe 2 possessions to score 11 points with the amount of time we had left on the clock. That means we can't come away without scoring points in either of those 2 possessions. And what happened? We didn't score any points, and essentially ended our chances of being able to tie the game up, despite having what would appear to have been another possession left.
It doesn't really matter which we score first, because we know we have to score a FG, TD, and a 2-point conversion. Granted, scoring the TD and 2-point conversion would be great, because we would only have to kick a FG on our last possession, but getting stopped on 3rd and 1 ensured that kicking the FG was our safest bet on 4th and 1 to keep our chances alive during our last possession.
If you don't score any points on the first of the 2 possessions, you essentially end your opportunity to tie the game, without even getting to the 2nd possession. You have to call the play that gives you the best chance to score points, and allows you to still tie it up with the 2nd possession.
Kicking the FG is the surest way of getting to that 2nd possession to be able to tie it, because running or passing it on 4th and 1 present more inherent risk of not getting the 1st down.
