Eagles at Raiders, Week 7 2021: who deserved to win?

The Raiders beat the Eagles 33–22, and it was no fluke: replayed with the way both teams actually played, the Raiders win 9 of 10. The Eagles had the bounces: judgment calls alone were worth 5.2 points to the Eagles.

Before kickoff it was a pick’em. The biggest swing (Q1, 7:11 left): the Raiders converted 3rd & 15, worth 11 points of win probability to the Raiders.

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.

How likely each kicker was to make that kick (his own record, the distance and the weather), and what happened.

  • D. Carlson, 28 yds made · 97% expected
  • D. Carlson, 39 yds made · 89% expected
  • Extra point missed · 95% expected

How much of each is luck?

0% treats it as skill, 100% as pure luck. The tick is our fit.
