FLYING WEDGE FORMATION, 1904-05
The 1904 Carlisle Indians team is seen here forming a flying wedge. That formation, designed to provide a wall of blockers, was soon outlawed because it resulted in many serious injuries.
Coach Pop Warner (in the background wearing a stocking cap) was known for the many innovations and tricks he introduced to the game. Among them were numbered jerseys, the screen play, single wing and double wing formations, the use of mud cleats on football shoes, the body block and various types of protective padding.
Some of Warner's tricks that were later banned included sewing a football-shaped leather patch to the chest of each player's jersey; the "hunchback," in which the ball is stuffed under the ball-carrier's jersey; having a receiver run off the field behind the opponent's bench and then back on to catch a pass; and sewing straps to either side of the backs' uniforms so players could be grabbed and thrown over the line.
