Week 6, Dolphins at Titans
4th-and-2, 6:05 remaining in 4th quarter, Down by 21
The Titans went for it on a 4th-and-2 on their 47. It doesn’t matter to NYT 4th Down Bot.

No matter what happens on this play, the Titans will almost certainly lose the game. In situations like these, what happens on this down is basically inconsequential, so there's no real recommendation here. (In fact, I’m taking a break from the game for a spot of Earl Grey.) Here’s the breakdown for the Titans’ scenario.

Where did these numbers come from?

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.
