User:Improvjam/Hb stretch

A stretch is a type of play in American Football in which the offensive line attempts to block towards either sideline. As the name suggests, the goal is for blockers to stretch the defensive line out, giving the ball carrier options as to which gap to run through. The quarterback usually takes a few steps towards the play before handing the ball off, giving the ball carrier a head-start. The ball carrier (usually a running back) attempts to rush down the line and either (A), reach the corner, about a yard outside the furthest blocker or (B), cut through an opened gap. This play is usually run without a lead blocker, although it can be used with a fullback/alternate halfback as an additional line blocker. The stretch is different form the HB sweep in that the runner has an option to "read" the defensive line, reacting to the direction the defenders pursue, and then choose a gap to run through. The play is characterized by a zone blocking scheme that relies on athletic linemen to push the line and not allow backfield penetration. Runnnig backs used in this system are usually faster running backs that make decisive cuts. One team that regularly uses the zone strech is the NFL's Indianapolis Colts.
