Raiders at Panthers, Week 1 2020: who deserved to win?

The Raiders beat the Panthers 34–30, and it was no fluke: replayed with the way both teams actually played, the Raiders win 9 of 10. The Panthers had the bounces: kicks alone were worth 10 points of win probability to the Panthers.

Before kickoff the Raiders were 59% favorites. The biggest swing (Q4, 1:23 left): the Panthers were stopped on 4th & 1, worth 22 points of win probability to the Raiders.

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.

How 4,000 replays ended

Raiders win 86% of them, Panthers 14%, counting the 1% still level after regulation as half each. The line is what actually happened: Raiders by 4.

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 +3.7 points to the Raiders: the final margin was Raiders by 4, without the luck Raiders by 0.3. 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 the weather), and what happened.

  • J. Slye, 47 yds made · 77% expected
  • D. Carlson, 20 yds made · 98% expected
  • J. Slye, 46 yds made · 79% expected
  • J. Slye, 31 yds made · 96% expected
  • D. Carlson, 54 yds made · 62% expected
  • Extra point missed · 93% expected
Bar: expected chance of a make. Filled dot: made. Open dot: missed or blocked.

Penalties: Raiders 3 for 40 yards, Panthers 5 for 65 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

Missing players

Key players (usually on the field for half the snaps or more) who missed this game or part of it, valued by position and quality. The same players are missing in every replay, so this counts as luck in points only.

  • Dennis Daley (CAR G), out · 0.3 pts
  • Tyrell Williams (LV WR), out (IR) · 0.6 pts

Raiders 86% · Panthers 14% unchanged: why
How much of each is luck?

0% treats it as skill, 100% as pure luck. The tick is our fit.

What counts

We tested momentum on 19,000 lucky breaks and found none, so it's off by default. Why

Flip a play

Force the other outcome, in this game and in every replay: a made kick becomes a miss, a stop becomes a conversion, a flag goes the other way.
