Week 1, Chiefs at Texans
4th-and-21, 8:30 remaining in 4th quarter, Down by 18
The Texans punted on a 4th-and-21 on their 9. It doesn’t matter to NYT 4th Down Bot.
If you disagree

To be honest, I've kind of checked out at this point. I hate to be the bearer of bad news, but the Texans’ chances of winning are pretty slim no matter what they do. So why not go for it?

Here's the full breakdown of my calculations:

What happened

Shane Lechler punts for 49 yards to KC42.

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.
