Mtn Deep Post lines up out of Shotgun Bunch Str Offset with 11 personnel and uses pre-snap motion to shift the bunch look before the snap. At the snap the outside receiver from the bunch runs a deep post to attack the middle of the field while the inside receiver from that stack works a corner route to clear the deep third and stretch the safety. The two remaining receivers on the other side run a shallow drag and a deep out, giving the quarterback a levels concept underneath if the post is capped. This is a man beater built to punish single high safety looks and press man coverage, with the primary read progression going post first, then corner, then working down to the drag and out combo underneath if the deep shots are not there.
Watch the free safety alignment pre-snap, if he is shaded to the play side or rotates down into the box the post has room to work against single high. Key the corner over the bunch at the snap, if he sneaks inside with the post release the defense is likely running man match or trail technique. If the deep corner route from the bunch stack pulls a linebacker or nickel defender out wide, that confirms man coverage and opens a throwing lane for the post behind him. Look for a robber or lurking linebacker sitting in the middle of the field, this defender is designed to jump the post route and can bait a bad throw. Versus zone blitz calls with two deep safeties splitting the field, the post will be capped, so check down quickly to the drag or out route before the pocket collapses.
Motion the bunch receiver pre-snap to see if the defense shifts or if a defender follows across the formation, this tells you man versus zone instantly.
If the corner shows single high safety with the post man uncovered off the snap, take the deep post shot immediately instead of waiting on the progression.
Use the drag and out combo as your answer versus zone coverage or when the safety rotates over the top to take away the post.
Best called on second and long or third and medium when you need a explosive play but still have a checkdown built in versus zone blitz pressure.
Pair this with Mtn Slot Post or HB Mtn Trail Dbl Post from the same set to keep defenders guessing on which receiver gets the deep shot after showing similar bunch motion.
