Panthers at Saints, Week 7 2020: who deserved to win?

The Saints beat the Panthers 27–24, but it was a coin flip: replayed with the way both teams played, the Saints win 4 of 10. Luck ran their way: kicks alone were worth 3.0 points to the Saints.

Before kickoff the Saints were 70% favorites. The biggest swing (Q4, 2:00 left): J. Slye missed 65-yard field goal, worth 29 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

Panthers win 57% of them, Saints 43%, counting the 9% still level after regulation as half each. The line is what actually happened: Saints by 3.

Where the luck was

Take the luck out

The final margin was Saints by 3. Remove the luck, one kind at a time, and it becomes Saints by 3.9.

Each row takes one kind of luck out of the margin. Color shows which team it helped. Luck shares are the fitted ones (how much of each component is luck).

The kicks

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

  • J. Slye, 43 yds made · 85% expected
  • W. Lutz, 41 yds made · 88% expected
  • W. Lutz, 43 yds made · 85% expected
  • J. Slye, 65 yds missed · 54% expected
