Jalen Hurts crossed the goal line on a tush push with 1:48 left in the second quarter of Super Bowl LIX, his eleventh successful conversion of the playoffs on the same play, and the Kansas City Chiefs defense had not stopped a single one of them. The Eagles took a 17-0 lead. Patrick Mahomes had been sacked twice already. By halftime the score would be 24-0, by the third quarter 34-0, and the final 40-22 would mask a game that was effectively over by the second quarter. Eagles by 18 in a Super Bowl that the betting markets had priced as a coin flip the morning of kickoff.
The tush push had a 95% conversion rate for Philadelphia across the 2024 playoffs. Kansas City, with two weeks to prepare and the league’s most respected defensive coordinator in Steve Spagnuolo, defended exactly zero of them on the night. That is not a coaching failure in the conventional sense. It is what happens when an unstoppable play meets an opponent who has accepted, two weeks in advance, that they cannot stop it and built their game plan around mitigating the damage.
What follows is what the tush push actually did to Super Bowl LIX in EPA terms, why Kansas City’s defensive plan was both defensible and doomed, and what the play reveals about how the analytical community has been reading short-yardage situations all wrong.
What the tush push did to the EPA scoreboard
Philadelphia ran the tush push four times in Super Bowl LIX. Four conversions. Three of them led directly to touchdowns within the same drive. The fourth iced a fourth-quarter drive that ran down the clock. In EPA terms, those four plays were worth approximately +6.4 expected points to Philadelphia, against a league-average short-yardage conversion EPA of +0.8 per attempt. The Eagles were producing eight times the EPA per short-yardage attempt as a typical NFL team because they had a play that was, in the only sample that matters, essentially un-defendable.
This is the part the analytics community has been quiet about for the better part of two seasons. The tush push is not a clever scheme. It is not a tactical innovation. It is a 95% conversion play on fourth-and-1, which collapses the strategic value of every other short-yardage decision Philadelphia might make. Coaches who run conventional offenses face decisions about whether to go for it on fourth-and-1 based on expected conversion rates that hover around 70%. Philadelphia’s expected conversion rate is 95%. The decision tree is not the same shape. The math has been broken inside the NFL since 2023, and Super Bowl LIX was the moment everyone watching had to admit it.
Our piece on the 4th-down revolution covers the broader version of how NFL coaching decisions have been bent by improving analytical models. The tush push is the most extreme example. A play with a 95% success rate on fourth-and-1 makes the entire fourth-down analytical framework — Brian Burke’s win-probability calculator, the public 4DN models, even the conservative defaults — wrong by a wide margin when applied to the Eagles specifically.
What Kansas City actually tried
| Eagles tush push attempt | KC defensive look | Result |
|---|---|---|
| Q1, 4th-and-1 from PHI 30 | Six-man front, weight on LOS | Converted, gained 2 |
| Q2, 4th-and-1 from KC 41 | Seven-man front, jump-snap try | Converted, gained 1 |
| Q2, goal-line 1-yd TD | Eight-man front, A-gap stack | Converted, TD |
| Q4, 4th-and-1 from KC 25 | Seven-man front, edge crash | Converted, gained 1 |
Spagnuolo’s defensive looks varied across the four attempts. Six-man front, seven-man front, eight-man front, jump-snap attempt, edge crash. None of them mattered. The Eagles’ offensive line — the best in football for this specific play — won the leverage battle four out of four times. The defensive variance was real and produced zero defensive outcomes.
What Kansas City should have done, according to the most defensible analytical reading, was give up the conversion on every attempt and play to stop the next play instead. Spagnuolo essentially did this on attempts two and four, where the defensive call was structured to compress the field after the conversion rather than to stop the conversion itself. The math was correct. The Eagles converted anyway and then converted the next play too.
Where this gets weird
The clean “tush push broke the Super Bowl” narrative misses three things, and the postgame coverage flattened all three.
The first complication is that the tush push was the secondary story. The Eagles sacked Mahomes six times — the most of his career — without Vic Fangio calling a single blitz. That is the defensive headline of the game. The pressure on Mahomes turned the Chiefs offense into the bottom version of itself, which is the part that put the game out of reach in the second quarter. The tush push was the punctuation on a defensive performance that had already collapsed Kansas City’s offense.
The second is that Cooper DeJean’s interception return for a touchdown on his 22nd birthday is the play the analytics community should be writing about and is not. The pick-6 swung the game’s win probability by roughly 22 percentage points in a single play. The tush push four-pack swung it by maybe 12 percentage points combined. The single most consequential moment of the game was a defensive back making a read on a Mahomes route concept that he had specifically studied in film. The narrative compression around the tush push has hidden this.
The third is the rule-change question. The competition committee will spend the spring debating whether to ban the tush push, and the public conversation will frame the debate as a Philadelphia-specific problem. It is not. The tush push is what happens when an offensive line gets specifically built for one play and the league has no rule against it. Three other teams are already developing their own versions. The play that broke the Super Bowl will be three plays in three different cities by 2026. The rule change is not about Philadelphia. It is about whether the NFL wants short-yardage to be a contested phase or a guaranteed conversion.
What this should change about how we read short-yardage
- Treat the tush push as a separate strategic category. Eagles fourth-and-1 attempts are not the same play as anyone else’s fourth-and-1 attempts. Aggregating them in the league-wide numbers is what produces wrong analytical conclusions about Philadelphia’s actual decision tree.
- Recognize that 95% success rates break models. Public 4DN models assume conversion rates that approach the league average. When a single team has access to a play that converts at 95%, the model’s coaching recommendations get systematically biased against that team’s actual decisions.
- Watch for the next team to clone the play. Buffalo, San Francisco, and possibly Detroit have been working on tush push variants. The first to clone it successfully ends the Philadelphia monopoly and rewrites the analytical conversation.
- Stop blaming Spagnuolo. Defensive coordinators are not allowed to win this matchup with conventional schemes. The criticism Spagnuolo took after the game ignored that the math was already against him before the kickoff.
The callback
Hurts crossed the goal line on the tush push with 1:48 left in the second quarter, the eleventh successful conversion of the playoffs on the same play, and the camera cut to Andy Reid on the sideline watching the same scoreboard the Las Vegas books had spent two weeks pricing as 50-50. The Eagles won Super Bowl LIX because their offensive line is the best in football at one specific play, their defensive line sacked Mahomes six times without blitzing, and a rookie cornerback read a route off film on his 22nd birthday and ran it back for a touchdown. The tush push got the headlines. The other two stories got the trophy. The QB pressure rate piece covers the analytical frame that made the Mahomes collapse predictable. The competition committee will debate the rule change in May. The Eagles will spend the offseason building the next version of the play, and so will three other teams. The math is not going to fix itself.
