Oregon scored with 10:25 to play, putting them up four. According to that chart, the would need to have between a 49%-50% probability of converting to go for two. They were three for six coming into the game so they were right on the line. And if they felt they had a better probability, then the play would have been to go for two.Yeah, there is almost no one in the coaching profession that would agree with you.Going for two when they went up 32-28 late in the game is a fireable offense in my opinion. You need the ONE point so a turn around FG after a Nebraska TD wins you the game. You only need ONE point. Two points gives your ZERO ADVANTAGE over one point, and the conversion rate is something like 65% less.
Instead, he they didnt convert, and a turn around FG after a Nebraska TD would have only tied the game.
I would fire a coach for that decision. Basic 3rd grade math and mechanics of football scoring system that pee wee football players understand.
You go for two to get ahead by six so the other team has to score a TD and also make their own extra point to beat you. The difference between a four and a five point lead at that point really doesn't mean much. The other team has to score a TD (a FG doesn't do them any good) and that would be enough to get ahead either way.
You give yourself two outs - either stop them to win or stop the PAT to tie. You don't assume you'll still have time to score again yourself.
there is not a coach in the game that game plans around the other team missing the extra point. you assume a touchdown is 7 points. the difference between a 4 and 5 point lead is huge late in the game. the difference between a 5 and 6 point lead is meaningless that late in the game.
so you have the same potential outcome in either situation..... stop them (win either way) or they score a TD and two outcomes 1) 98% you are down by 2 and 2% you are down by 3 (kick extra point outcome) or 2) 30% you are down by 1 and 70% you are down by 3 (go for 2 outcome)
Every coach in the world would choose option 1...except Helfrich.
EDIT:
its just basic math...

I'm not sure that really counts as "basic math" when it in includes a number that can be open to interpretation. Based on whose interpretation of what variables? All conversion attempts? Just by their regular offense? Throw out your conversions against non-Power 5 opponents?
Most regular charts say to go for two when up by 4.
