One of those aspects of the game that has evolved is the quarterback sneak that has now become popular with the Philadelphia Eagles, as they line their quarterback under center and then have two backs lined up behind him to push while the offensive line appears to go low,

The Baltimore Ravens also used their tight end, Mark Andrews, to convert a fourth-down Tush Push against the Eagles on Dec. 1. And that was despite having the NFL's best running quarterback in Lamar Jackson and running back Derrick Henry, who ran for 1,923 yards, second only to the Eagles' Saquon Barkley.

Eagles head coach Nick Sirianni called talk of banning the tush push play that his team has made a staple of their offense "unfair" earlier this week and took particular aim at arguments that the play was unsafe.
