### Playoff Implications - Week 4

Here is your week 4 guide to playoff implications. The purpose of this feature is to highlight games that have a significant impact on the playoff picture (see this post for background).

The playoff implications below are derived from the same simulation I run to calculate playoff seed probabilities for my daily NFL rankings. I can group the simulation runs by the outcome of each game and then see how a team's playoff chances vary between the two groups. The interactive table at the bottom of the post will allow you to see corresponding results for any game or team.

### Ranking Week 4 Games by Leverage

The table below ranks the week 4 games by total leverage. Leverage in this context is a measure of both how uncertain a game's outcome is (games between evenly matched teams have higher leverage) and how much the playoff picture swings as a result of that outcome.

GameLeverage
CAR @ BAL 25.2%
GB @ CHI 24.7%
BUF @ HOU 24.5%
NO @ DAL 23.4%
PHI @ SF 23.0%
DET @ NYJ 20.5%
TEN @ IND 19.2%
ATL @ MIN 17.7%
NE @ KC 16.3%
NYG @ WAS 10.4%
TB @ PIT 9.3%
JAC @ SD 8.2%
MIA @ OAK 5.9%

### Beyond Week 4

We can also use the simulation dataset to look ahead to the remainder of the season and see which games (based on what we know now) will have significant playoff implications. The table below shows the top 10 week 5-17 games by total leverage.

15 PIT @ ATL 28.9%

9 ARZ @ DAL 28.3%
15 NO @ CHI 28.3%
6 CHI @ ATL 27.2%
7 HOU @ PIT 27.1%
13 NE @ GB 27.0%

### Week 4 Cheat Sheet

And here is your cheat sheet for week 4. You can filter by game or team below. I have already filtered out any games that aren't statistically significant to a team's playoff chances.
