The Eagles eventually moved the deep man of the victory formation to the line of scrimmage. The ultra-condensed formation became the team's signature. No one could mistake it for another play. Defenses began pinching in their linemen, and often lining up offsides. It didn't matter.

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.

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.

Should this play be banned? But the success we have is not replicated always throughout the entire league," Sirianni said.

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."
