Two plays from the Cowboys-Eagles rivalry have resurfaced this week, each remarkable in its own way for what it reveals about how rare certain football outcomes actually are.

The first: Dak Prescott finding T.Y. Hilton to convert a 3rd-and-30 during the 2022 season. Hilton had signed with the Cowboys in December 2022 after spending his entire career with the Colts, and the play is believed to have come from the Week 16 matchup against the Eagles on December 24, 2022 — a 40-34 Cowboys win. Prescott connected with Hilton for roughly 33 yards on a 3rd-and-30, keeping a drive alive in what became a pivotal fourth-quarter sequence.

The statistical improbability of that conversion is worth pausing on. Third-and-30 situations are extraordinarily rare to begin with, and the historical conversion rate on 3rd-and-30 or longer sits near 1-2%. Most teams in that situation run a draw play, punt, and move on. The Cowboys instead attacked downfield and succeeded — a outcome that defies standard expected value calculations.

The second play involves the inverse: a defensive standout. Derek Barnett, the Eagles’ first-round pick (14th overall) in the 2017 draft, strip-sacked Dak Prescott, with linebacker Nigel Bradham scooping the fumble and returning it for a touchdown. Both Barnett and Bradham were on the Eagles simultaneously from 2017 through 2019, meaning the play occurred during one of those regular-season rivalry matchups. The exact game has not been independently verified from available sources, though it falls within the 2017-2019 window when both players shared the Philadelphia roster.

A strip-sack returned for a touchdown is one of the highest-leverage defensive plays in football. It combines a turnover — already worth roughly 4 points in expected value — with an immediate score, typically producing a swing of 10 or more points in expected points added depending on field position. It is the defensive equivalent of a pick-six, and like that play, it shifts game script in a way few other single snaps can.

Bradham played for the Eagles from 2016 through 2019 after stints with the Bills. He was a key defensive piece during the Eagles’ 2017 Super Bowl run. Barnett, meanwhile, was a rotational edge rusher who showed flashes as a rookie and developed into a larger role over subsequent seasons.

What connects the two plays beyond the rivalry is their statistical character. One is an offensive play that should almost never work. The other is a defensive play that, when it does work, produces one of the largest single-play swings the sport offers. Both belong to the Cowboys-Eagles ledger — a rivalry that has produced its share of routine plays and a handful that defy the percentages.

The 3rd-and-30 conversion remains one of the least likely offensive successes in recent NFL memory. The strip-sack touchdown remains one of the most impactful defensive plays a team can produce. That both came from the same rivalry is either coincidence or a reflection of how often these two teams have played each other in high-leverage moments.

Today, he wields expected points and win probability to dismantle locker-room cliches, politely pointing out whenever the narrative stubbornly refuses to align with the data.
