There was a time when pushing your teammate from behind was outlawed in the NFL. The league changed the rule in 2005 to allow pushing from behind, but teams weren’t really taking advantage of it until the Philadelphia Eagles popularized the “Tush Push” play with quarterback Jalen Hurts.
In short-yardage situations, the Eagles have several players line up behind Hurts and push him beyond the line to gain. Using the play, Hurts went 36-of-40 on quarterback sneaks last season.
