The Philadelphia Eagles have one of the most unstoppable plays in football, a play that teams have tried to get banned in the past to no avail. The "Tush Push" has been the signature play of the Eagles' run over the last three seasons,

Tyson adds that force is equal to mass acceleration, i.e., more mass means a force is harder to stop. The Eagles have quite a lot of mass in their offensive line, leading to a force that’s very difficult to stop from crossing the goal line.

The Eagles ran the quarterback sneak out of variations of that singleback look until Week 5. That week, they ran six sneaks against the Arizona Cardinals. The formation de jour was a three-man I-formation in which the first back served as Hurts' pusher. The Eagles converted five of six sneaks for first downs, including two touchdowns.

In the fourth quarter of the AFC championship game, the Buffalo Bills were nursing a 22-21 lead over the Kansas City Chiefs when they faced a fourth-and-1 on the Chiefs’ 41-yard line.

The play, also known as the "Brotherly Shove," has been so successful, so rewarding that even renowned physicist Neil deGrasse Tyson once deemed it nearly unstoppable from a physics perspective.

No one does the quarterback sneak, or so-called "tush push," better than the Eagles, so the Chiefs defense's only answer is to avoid short-yardage situations.

Even Neil deGrasse Tyson says that the Eagles' vaunted Tush Push is unstoppable. But one Kansas City coach says "any play can be stopped."

Both the Eagles and Chiefs boast elite talent, but the Birds have perfected a game-changing play. Crucial for securing first downs, the maneuver is rooted in physics.
