 Its goal is to disconcert a defensive front in order to allow a quick screen pass to a wide receiver with six blockers, or to allow a short run by the running back.Surprise is the main goal of the play, and it is not typically run outside of short-yardage situations.The play, originally formulated in the 1930s, still retains a modicum of popularity on high school and college teams, where the lesser athleticism of the players will allow the play to be performed with a greater degree of success.
