The coach and I agree that attempting a field goal is the thing to do here, but you may be thinking it makes sense to go for it. That would be the right call if you think the Broncos’ chances of converting on fourth down are at least 34 percent. But based on my analysis, I’d give the Broncos only a 24 percent chance to get a first down here.
Here's the full breakdown of my calculations:
|Option||Chance of converting||
Chance of winningBefore play
|Field goal try28 yard kick (est.)||93%||33%||33%||-|
|Go for it4th and 10, opp. 11||24%||33%||31%||–2%|
Along with some circuitry to come up with a win probability for every game situation, all you need to figure out what you should do next is an estimate of how likely you are to make a field goal or convert a first down.
My estimates for these are based on the results of thousands of similar plays, but you may think you're smarter than I am. This chart shows you how changing those estimates would change my recommendation.
|Field goal try||85% of the time|
|Go for it||15% of the time|
Brandon McManus 29 yard field goal attempt is GOOD. Brandon McManus 29 yard field goal attempt is GOOD.
To estimate a team’s chances of winning, I use a mathematical model that accounts for a whole lot of variables — including the difference in score, the time remaining in the game, and the number of timeouts each team has left. On top of that, I have models for the likelihood that a team makes a field goal and the likelihood that it will convert a first down.
By combining all of this information, I can come up with the best decision a team can make, according to math.
