Jets at Washington, Week 11 2019: who deserved to win?

The Jets beat Washington 34–17, and it was no fluke: replayed with the way both teams actually played, the Jets win 9 of 10. Washington had the bounces: fumble bounces alone were worth 4.7 points to Washington.

Before kickoff it was a pick’em. The biggest swing (Q2, 13:55 left): Offensive Holding on Washington, 5 yards, wiping out the play, worth 17 points of win probability to the Jets.

Three other ways to ask

Each answers a different question, so none of them replaces the replay above.

The closing betting line, turned into a probability. What everyone knew before the game.

The line plus what this game showed, weighted by how much one game can tell. It stays close to the line because one game says little.

Every kick, fumble bounce, drop, conversion and judgment call redrawn; everything else fixed. The narrowest view of luck.
