Mtn Zone is a zone stretch run out of the I Form Wing Over set with 22 personnel, built to attack the edge with a fullback lead blocker and a wing tight end sealing the perimeter. The line executes a zone blocking scheme, stepping in unison to the play side to create cutback lanes while the fullback and wing handle the edge defender and any flowing linebacker. The primary read progression starts with the play side defensive end or edge defender: if he crashes down hard, the HB presses the hole and cuts back behind the fullback's block, and if he stays wide, the back rides the zone track through the designed alley.
Identify the box count before the snap, six or fewer defenders in the box signals a favorable numbers advantage for the zone scheme to work. Watch the play side linebacker's depth and shoulder angle, a linebacker sitting flat footed or crashing hard down the line opens a clean cutback lane behind the fullback's block. Check safety rotation post-snap, if the defense rotates a safety down into the box pre-snap or shows run blitz pressure off the edge, expect the cutback to be taken away and consider bailing to a pass concept instead. Zone Mtn Zone struggles against gap exchange or scrape exchange linebacker techniques designed to defend both the frontside and cutback lanes simultaneously, so look for linebackers reading mesh point key rather than committing early. User controlled defenders flying downhill to string out the fullback's block are the biggest threat, if you see a user linebacker sitting outside the tackle box pre-snap, expect an aggressive edge set that forces an early cutback read.
Run this on early downs in base personnel sets when the defense shows a two high or single high shell without extra defenders in the box, since Mtn Zone thrives against light fronts of six or fewer in the box.
Pre-snap, check the position of the Sam or Will linebacker relative to the wing tight end, if that defender is walked up tight to the line expect a quick flow read and be ready to cut back immediately off the fullback's block.
User the fullback briefly after the snap to help widen or seal the edge defender before releasing to the second level, this manual assist creates a cleaner cutback lane against aggressive user driven pursuit.
Pair Mtn Zone with PA Waggle and PA Boot Flow from the same set, the identical I Form Wing Over alignment and fullback action sells the run fake and forces linebackers to hesitate on their zone drops.
Avoid calling this into stacked eight man fronts or heavy blitz looks, since the zone scheme lacks the numbers to handle extra rushers crashing downhill before the back can locate the cutback lane.
