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, conversion and judgment call redrawn; everything else fixed. The narrowest view of luck.

An off day for Texas State

Its offense played far below its usual level. In a fresh game against Arkansas State it would win 82% of the time; with this day’s form, 50%.

31 points apart for Texas State: the gap is how differently this game went from what the two teams usually are.

UnitThis gameUsual levelBetter or worse than usual
Texas State offenseEPA per play gained +0.06 +0.16 worse by 0.10
Texas State defenseEPA per play allowed −0.11 +0.11 better by 0.22
Arkansas State offenseEPA per play gained −0.11 +0.02 worse by 0.13
Arkansas State defenseEPA per play allowed +0.06 +0.10 better by 0.04

EPA (expected points added) per play on competitive snaps, turnovers left out because they are valued as luck. Usual level: the team’s earlier games this season plus half of last season, pulled toward the league average. One team’s defense and the other team’s offense are the same snaps, so one game can’t fully say whose day it was; it shows how far this one was from both teams’ norms.

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.

Swings add up across a game, so in one that went back and forth they can pass 100%. On the scoreboard the same luck was worth +7.9 points to Arkansas State: the final margin was Arkansas State by 1, without the luck Texas State by 6.9. Luck shares are the fitted ones (how much of each kind is luck).

The kicks

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

  • C. Van Andel, 51 yds made · 54% expected
  • T. Robles, 31 yds made · 86% expected
  • Extra point missed · 98% expected
Bar: expected chance of a make. Filled dot: made. Open dot: missed or blocked.

Penalties: Texas State 9 for 65 yards, Arkansas State 5 for 40 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
