Dbl Mtn Inside Zone Split is a zone run play out of Shotgun Wing Slot Offset with 12 personnel, featuring double mountain tight end alignment on the same side and a split zone blocking element. The offensive line executes an inside zone blocking scheme while one of the tight ends works across the formation to cut block or seal the backside edge defender, creating a natural gap for the running back to press. The primary read progression starts with the play side double team at the point of attack, then bounces to the backside cutback lane if the split flow tight end seals his defender and the backside gap opens up.
Identify the box count before the snap, if the defense has six or fewer defenders in the box, the inside zone should have a favorable numbers advantage for the offensive line Watch the play side defensive end and see if he is crashing hard down the line, since that key tells the running back to bounce outside off the double team rather than press straight ahead Key the backside linebacker for run blitz timing, if he is stepping up early before the snap, that defender is likely shooting a gap and the cutback lane behind the split zone tight end becomes the better path This play struggles against gap exchange or scrape exchange defensive calls, since those stunts are designed to counter zone blocking by having the end and linebacker trade responsibilities Look for a user controlled linebacker sitting in the middle of the box, since a spy or lurk defender can plug the cutback lane that the split zone block is designed to create
Use pre-snap motion sparingly on this play since the double mountain alignment already stresses the defense with extra gap conflict, and adding motion can tip your run intent to a heads up defense
Check the linebacker depth before the snap, if both linebackers are sitting tight in the box with no spacing to the play side, this is a green light to run it since numbers favor inside zone
Hot route the fullback or second tight end into a chip block if you see a slanting defensive line, since a slant into the play side gap can blow up the initial double team
Pair this play with Dbl Mtn PA Slide or Dbl Mtn PA Slot Corner in the same set to keep run and pass action visually identical from the same double mountain look, forcing linebackers to hesitate on run fits
Run this on early downs in normal or heavy boxes, but avoid it against six or seven man fronts unless you have a clear cutback lane read, since the split zone block can get overwhelmed by extra defenders in the box
