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.
- A. Birr, 49 yds missed · 59% expected
- A. Birr, 34 yds made · 84% expected
- A. Birr, 26 yds made · 93% expected
- A. Birr, 23 yds made · 95% expected
Penalties: Georgia Tech 6 for 34 yards, Boston College 3 for 25 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
