Down three with just a few minutes remaining in the game, Notre Dame was pushing the ball deep into Louisville territory and had a chance to take a late lead with a go-ahead touchdown. Facing second and goal from the nine yard line, it appeared the Irish would at the very least tie the game and send it to overtime. But Notre Dame quarterback Everett Golson was sacked on second down, and threw incomplete on third. Then kicker Kyle Brindza missed a chip-shot field goal, and down went Notre Dame. According to fantasy sports app Pivit, the field goal is the costliest play of the week, but the whole series is a disaster, in an interesting way. It'd be the second week in a row the Irish screwed themselves during crunch time, extending their losing streak to three games after a promising start to the season.

Pivit tracked in-game Win Probability for all college football games involving ranked teams this weekend. Their Win Probability is similar to Brian Burke's, but places more emphasis on team strength. Before Notre Dame's costly series of plays, an Irish victory appeared likely. But the sack on Golson lowered Win Probability 23 percentage points from 81 percent to 58 percent. Golson's incomplete pass reduced WPA 21 percentage points from 58 percent to 37 percent. And the missed field goal lowered WPA 37 percentage points from 38 percent to 1 percent. As seen in the chart below, near the end of the game, the Irish's chance at winning fell off a cliff.

But the drop as a whole is what's interesting, in that it came in three parts. The sack made overtime much more likely, but once the incomplete pass came in, with about a minute left and stopping the clock, the odds shifted drastically because the Irish now were going to attempt to tie—which as we saw is uncertain—and then give Louisville a chance to drive and kick a game-winner of their own, or possibly try their luck in overtime. These things happen on every late drive, but it's interesting here because we see three different permutations come out of three consecutive plays.

Below are the most and least helpful plays of the week.
