49ers at Cardinals, Week 11 2025: who deserved to win?

The 49ers beat the Cardinals 41–22, and the replays lean their way: with the same day's form, they win 8 of 10.

Before kickoff the 49ers were 60% favorites. The biggest swing (Q3, 12:56 left): Offensive Holding on the Cardinals (Pharaoh Brown), 9 yards, wiping out the play, worth 14 points of win probability to the 49ers.

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

49ers win 76% of them, Cardinals 24%, counting the 2% still level after regulation as half each. The line is what actually happened: 49ers by 19.

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 +13.3 points to the 49ers: the final margin was 49ers by 19, without the luck 49ers by 5.7. 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.

  • C. Ryland, 58 yds missed · 61% expected
  • C. Ryland, 26 yds made · 97% expected
  • E. Pineiro, 48 yds made · 82% expected
  • E. Pineiro, 47 yds made · 85% expected
  • E. Pineiro, 47 yds made · 85% expected
  • Extra point missed · 94% expected
  • Extra point missed · 94% expected
Bar: expected chance of a make. Filled dot: made. Open dot: missed or blocked.

Penalties: 49ers 1 for 15 yards, Cardinals 17 for 130 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 half toward luck; pre-snap fouls, which repeat, don’t count.

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

What counts

None by default: our tests measured no carryover after a lucky break. Slide it up to count a break for more than its own swing. 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.
