Broncos at Saints, Week 7 2024: who deserved to win?

The Broncos beat the Saints 33–10 and were the better team on the day: replayed with the same form, they win 7 of 10. The Saints had the bounces: judgment calls alone were worth 4.8 points to the Saints.

Before kickoff the Broncos were 57% favorites. The biggest swing (Q2, 13:19 left): Defensive Offside on the Broncos (D.J. Jones), 5 yards, wiping out the play, worth 9 points of win probability to the Saints.

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.
