Raiders at Steelers, Week 16 2022: who deserved to win?

The Steelers beat the Raiders 13–10 and were the better team on the day: replayed with the same form, they win 8 of 10. The Raiders had the bounces: kicks alone were worth 4.8 points to the Raiders.

Before kickoff the Steelers were 57% favorites. The biggest swing (Q3, 2:18 left): Face Mask on the Raiders (Foster Moreau), 15 yards, wiping out the play, worth 16 points of win probability to the Steelers.

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.
