You remember the Tush Push, the short-yardage play in which offensive players line up in an old-fashioned rugby scrum and push a ball carrier through the defense. Put them in leather helmets and they will come full circle to the Flying Wedge (banned around 150 years ago).

After years of study by the NFL's competition committee and input from coaches, the "Tush Push" lives on. It's time to declare winners and losers.
