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.

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.

How 4,000 replays ended

Broncos win 67% of them, Saints 33%, counting the 2% still level after regulation as half each. The line is what actually happened: Broncos by 23.

Where the luck was

What the luck was worth

Every lucky and unlucky play, weighted by the moment it happened: its swing in win probability, added up by kind. A missed kick in a decided game counts for nothing; the same kick at the end of a tie game can be most of a win.

Swings add up across a game, so in one that went back and forth they can pass 100%. On the scoreboard the same luck was worth +8.2 points to the Broncos: the final margin was Broncos by 23, without the luck Broncos by 14.8. Luck shares are the fitted ones (how much of each kind is luck).

The kicks

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

  • W. Lutz, 46 yds made · 78% expected
  • W. Lutz, 32 yds made · 95% expected
  • B. Grupe, 35 yds made · 94% expected
  • W. Lutz, 52 yds made · 69% expected
  • W. Lutz, 38 yds made · 90% expected
Bar: expected chance of a make. Filled dot: made. Open dot: missed or blocked.

Penalties: Broncos 7 for 47 yards, Saints 5 for 35 yards

Every accepted flag, in order, and what it did to the helped team’s chance of winning at that moment, including any play it wiped out (points on the scoreboard in grey). A flag in a decided game is worth nothing; one at the turn of a close game can be worth most of a win. Judgment calls count toward luck, pre-snap fouls mostly don’t. How calls are valued
