Why don't all teams use the unstoppable tush push? Do Eagles have a 'secret ingredient'?

The article discusses the use of the "tush push" play by the Philadelphia Eagles, which has been highly successful for the team on fourth-and-1 situations. The tush push involves the offensive linemen pushing the ball carrier from behind, rather than traditional running plays. The Eagles have converted this play 96.6% of the time, which is significantly higher than the league average. The article explores why other teams don't adopt this strategy, despite its apparent effectiveness. Factors such as the unique skills and physicality of the Eagles' offensive line, as well as the element of surprise and deception, are cited as potential reasons for the play's success. The article suggests that the Eagles may have a "secret ingredient" that makes the tush push particularly effective for their team, but this approach may not be as successful for other NFL franchises. The article provides a concise overview of the tush push strategy and the Eagles' success with it, without delving into extensive details or making unsubstantiated claims.
