Jaguars at Broncos, Week 2 2026: who deserved to win?

The Broncos beat the Jaguars 20–13, but the replays call it close to a coin flip: with the way both teams played, the Broncos win 6 of 10. Luck ran their way: kicks alone were worth 10 points of win probability to the Broncos.

Before kickoff the Broncos were 57% favorites. The biggest swing (Q4, 11:11 left): the Jaguars converted 3rd & 8, worth 12 points of win probability to the Jaguars.

Our prediction before kickoff

We had the Jaguars by 1.3, 54% to win. The Broncos won by 7, a result we gave 46%. The final margin was 8.3 points from ours; 50% of games like this end further from the forecast than that.

Most of the distance between a forecast and a final score is luck: even with both teams’ strength known exactly, one game’s bounces, kicks and calls move the final margin by about ±12 points. This game was played before our forecasts went live, so this one was made afterwards, the same way, from only what was known before kickoff. How our predictions have done

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

Jaguars win 40% of them, Broncos 60%, counting the 3% still level after regulation as half each. The line is what actually happened: Broncos by 7.

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 +5.3 points to the Broncos: the final margin was Broncos by 7, without the luck Broncos by 1.6. 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.

  • W. Lutz, 20 yds made · 98% expected
  • C. Little, 44 yds made · 81% expected
  • C. Little, 23 yds made · 99% expected
  • W. Lutz, 45 yds made · 76% expected
  • C. Little, 54 yds missed · 66% expected
Bar: expected chance of a make. Filled dot: made. Open dot: missed or blocked.

Penalties: Jaguars 3 for 18 yards, Broncos 10 for 53 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.

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.

  • RJ Harvey (DEN RB), out · 0.2 pts
  • Patrick Mekari (JAX OL), out (IR) · 0.4 pts
