Inside Zone Blocking
--------------------------------------------------------------------------------
Inside zone blocking is designed to use the movement of the defenders against them as the running back finds the crease in the defense. Though inside zone plays are usually called to the guard or tackle holes (3,4,6,or 7), they can break open anywhere from tight end to tight end, depending on how the defense attacks.
Inside zone blocking rules allow linemen to use the movement and attack angles of the defenders against them. Whichever way the defender chooses to go, he is sealed off and the running back is prepared to cut off the block. Nebraska running backs are taught to attack the line-of-scrimmage (LOS) before cutting on inside zone plays. This gives the blocks the needed time to develop. The rule for the I-back is that his feet must replace the feet of the lineman before he can cut.
Inside zone blocking rules are keyed by whether a lineman is covered or uncovered. A covered lineman (one who has a defensive lineman aligned across from him) will execute a "stretch base" technique. This means he will take a short stretch step to the play side (step right on a 44, left on a 46) and attempt to control the playside shoulder of the d-lineman. The purpose of the stretch step is to invite movement by the d-lineman, then immediately engage him.
Uncovered linemen (no d-lineman across from them) execute a "stretch double" technique. Stretch double also calls for a stretch step to playside. The uncovered lineman then attacks the backside shoulder of the same d-lineman, creating double teams on most of the defensive linemen.
NOTE: the linemen operate on a system that moves to playside, NOT toward the hole called. On a 44 dive the play is called to the right guard, but the key is that it is a right side play. The right tackle's and right tight end's playside shoulders are their RIGHT shoulders even though the play was called to the left of them. The 4 hole is to the right side of the center, so right is playside for everyone on the line.
In executing the stretch double technique, the uncovered lineman assists the covered lineman to the playside; i.e., if a center and playside tackle are covered, the playside guard executes the stretch double with the tackle, NOT the center. If side-by-side linemen are both covered, the playside lineman is "on his own," and executes a stretch base block without double team help.
