Three other ways to ask
Each answers a different question, so none of them replaces the replay above.
Before kickoff
The closing betting line, turned into a probability. What everyone knew before the game.
Same teams, fresh 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.
Only coin-flips re-rolled
Every kick, fumble bounce, conversion and judgment call redrawn; everything else fixed. The narrowest view of luck.
How 4,000 replays ended
Minnesota wins 8% of them, Iowa 92%, counting the 3% still level after regulation as half each. The line is what actually happened: Iowa by 38.

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.
The kicks
How likely each kicker was to make that kick (his own record, the distance), and what happened.
- D. Stevens, 34 yds made · 84% expected
- D. Stevens, 46 yds made · 63% expected
- B. Denaburg, 34 yds made · 81% expected
Penalties: Minnesota 2 for 15 yards, Iowa 3 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

|---|---|---|
| Q2 6:59 | Holding on Minnesota, 10 yards | 0% IOWA +0.6 pts |

| Q3 3:10 | Unsportsmanlike Conduct on Iowa, 15 yards | 0% MINN +1.6 pts |
| Q3 1:36 | Offside on Iowa, 5 yards · pre-snap | 0% MINN +0.9 pts |
