Almost all coaching decisions basically come down to the same choice.
Passive vs Aggressive
95% of the time if there is any doubt whatsoever, coaches pick the passive route. Thats actually whats the matter with the NFL. Its also one of the reasons why Belichick is the most successful coach in the league. Coaches pick passive because they know that if they lose, they can pass the buck and say "I had confidence in ____. How was I suppose to know they were going to blow it?" They'll get a little bit of blame for a bad play call, but it stops there because ultimately somebody else will get the majority of the blame. They want to win the game. Who doesn't? But winning isn't the top priority. The top priority is making sure that somebody else takes the blame if you lose? A passive coach always has a scapegoat. An aggressive coach is the scapegoat.
Have no qualms about this. In coachspeak, "confidence" doesn't actually mean confidence. It means "not my fault".
Anyway, tonight Kubiak had the decision between aggressive and passive. He could throw for an extra 10 yards which would have greatly increased the probability of a successful kick. Or he could be passive and stand pat.
The ball was on the 32. That gave the kick about a 64% probability of success. Since a kick only tied the game, the WP was 32% (0.64 * 50% win in OT)
If he threw the ball to the 20, it would have been a 84% kick (42% WP).

Of course, there was the probability of a sack or an interception. A sack would have lowered the kick to about 40% (20% WP). An interception obviously would have made it 0% WP. Of course, there was also the possibility of a TD. A TD would have made it 99% WP.
So here are the probabilities of running a play in terms of relative gains in WP.
Interception = -32
Sack = -10
Incompletion = 0
Completion = +10
Touchdown = +67
I'm going to let you place the numbers into a spreadsheet and assign the various probabilities to them. Its too late and I don't feel like bothering to look up the numbers.
But I think I can see where I'm going with this. Whatever realistic probabilities you use, Kubiak made a huge error in not running a play there. Monumental error.
In contrast with the Belichick decision (which was actually the right decision), Kubiak very well might have made the worst decision of the year. Its hard to say. There is a lot of competition. In every single case, the coach made an ultra-passive decision.
Why did he do this? Why did he pass up such an obvious opportunity to increase the probability of winning the game?
Because "he had confidence in his kicker".
Translation: Blame the kicker not me.
I'm sure that all of the people that were arguing "passive was right because Belichick went aggressive and they lost" are now saying "aggressive was right because Kubiak went passive and they lost".
Still they argue it much louder when a coach is aggressive and loses. Thats why coaches almost always go passive even when it is the clearly inferior choice.
