Eagles' Tush Push Key to NFL Victory against Chiefs
More than 2500 kilograms of human flesh smash together to make a yard or two.
The "brotherly shove" or "tush push" has become synonymous with the Philadelphia Eagles and boasts the highest success rate of any play in the NFL, but only when executed by the Eagles.
Described as American football's "unstoppable move", it may be the one factor that prevents the Kansas City Chiefs from winning their third consecutive Super Bowl on Monday (AEDT).
The tush push is employed by the Eagles to gain small amounts of territory. A wall of players surge into the opposition, forcing open gaps in the defence, while the quarterback behind them is pushed into the gap to either score a touchdown or maintain a drive.
