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.

The final margin was Jaguars by 17. Remove the luck, one kind at a time, and it becomes Jaguars by 19.0.

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).

  • B. Grupe, 28 yds made · 96% expected
  • B. Grupe, 36 yds made · 90% expected
  • C. Little, 35 yds made · 93% expected
  • C. Little, 48 yds made · 76% expected
