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.

Where the luck was

Take the luck out

The final margin was 49ers by 10. Remove the luck, one kind at a time, and it becomes 49ers by 9.7.

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. Romo, 38 yds made · 90% expected
  • E. Pineiro, 55 yds made · 68% expected
  • E. Pineiro, 43 yds made · 84% expected
Bar: expected chance of a make. Filled dot: made. Open dot: missed or blocked.
