Mtn Double Post Reverse Dragon is a trick run play out of the Bunch Y-Flex set that disguises a reverse behind a double post concept up top, forcing the defense to declare between defending the deep shots and respecting the misdirection run action. The bunch alignment creates natural rub potential on the double posts, making this a strong Cover 2 and Cover 4 beater since both safeties can be manipulated by the two vertical posts splitting the deep middle or attacking the seams outside the deep half defenders. Your primary read is the reverse action first, but if the perimeter defenders crash down on the run fake, pull the ball out and go straight to your double post read since the safeties will already be compromised.
Watch for user controlled safeties who key the reverse motion instantly and stay home instead of flowing with the run action, since that removes your double post window. Cover 3 with a sky safety rotating down can be problematic because it adds an extra body to both the run fit and the deep middle, clogging both phases of this concept. Man coverage with press corners on the bunch receivers can disrupt release timing on the posts before the double move ever develops, so check corner alignment pre-snap. If linebackers show blitz or a nano blitz look pre-snap, the reverse action can get blown up before the fake even sells, so be ready to bail into the post read immediately off the snap. Defenses that sit two deep safeties at depth without biting on the run fake will still be vulnerable to both posts splitting the seams, so identify true Cover 2 shells and trust the double post over the reverse.
Run this on early downs like first and second and ten when defenses are more likely to sit in base Cover 2 or Cover 4 shells expecting a standard run or play-action look.
Check safety depth before the snap. If both safeties are sitting shallow at 8 to 10 yards, the double post window over the top opens up big because they have to respect run fits first.
Use the reverse action to bait linebackers and safeties into flowing toward the fake, then attack the vacated post window on the backside for an explosive gain.
Pair this play with HB Power or Inside Zone earlier in a series so the defense keys run action and gets caught flat footed when you actually pull the double post read out of the reverse fake.
Motion adjustments are limited on this concept, so lean on your pre-snap coverage recognition rather than hot routing receivers, since the design already manufactures the leverage you need against Cover 2 and Cover 4 shells.
