Mtn PA Boot RT is a play-action boot concept out of Pistol Y Off Trips that rolls the quarterback right off a run fake. The backside receiver runs a deep corner route while the trips side clears out with a receiver on a deep crosser and the flat route sitting underneath, giving the quarterback a high-low read as he rolls out. The primary read progression starts with the flat route on the boot side, then works to the deep crossing route coming from the backside, with the corner route as a shot play option if the coverage bites hard on the run action.
Key the linebackers immediately after the snap: if they bite on the run fake and flow toward the mountain action, the boot flat and deep crosser will be wide open. Watch the flat defender on the boot side, if he sinks with the crosser instead of stepping up, throw the flat route immediately for a free gain. Identify man coverage by checking if the cornerback on the backside follows the crosser across the field, that confirms man and opens up the corner route on a rub. Zone shells with a hard-flowing linebacker to the flat can shut this down quickly, so be ready to reset and check down if the flat is taken away. Watch for a blitz off the edge on the boot side, since the quarterback rolls right into pressure if the offensive line does not account for an overload look, so audible protection if you see a heavy box pre-snap.
Run this on early downs like first or second and short to mid yardage so the run fake actually holds linebackers and safeties.
Check the safety alignment pre-snap: if you see two high safeties sitting deep, expect the boot flat and crosser to be open underneath since the defense is playing pass first.
If the defense shows a single high safety or heavy box, trust the play-action fake and look to hit the corner route or the deep crosser behind closing linebackers.
Pair this with Mtn Wide Zone or HB Slam from the same set so the run fake sells and defenders start jumping run fits, setting up the boot for explosive gains.
Use manual motion pre-snap to check if the defense follows across the formation, that confirms man coverage and tells you the flat route or crosser will have a favorable matchup.
