Four Verticals out of the Shotgun Wide Y Trips WK set sends four receivers vertically up the field, stressing the deep middle and both boundaries at once. This is a pure man beater and Cover 2 beater, though it also punishes Cover 3 shells that get lazy zone drops, since the seams split the underneath defenders from the deep thirds. The primary read starts with the middle seam route out of the trips side, then works to the deep post or bender if the safety jumps the seam, and finally to the backside single receiver on a go route as the outlet against man coverage.
Watch for two deep safeties pre-snap, this signals Cover 2 or Cover 4 and tells you the seams are the priority read since the safeties must gain width to help outside. A single high safety pre-snap means Cover 3 or Cover 1, in this case key the deep middle defender because if he sits on the seam you should bend your route inside or outside him for a big gain. Post-snap, identify any user-controlled lurk defender sitting in the shallow middle, since a good user player will bait the seam throw and jump the route for a pick. Look for cornerback press alignment before the snap, if the corners are pressing man coverage the outside verticals become one-on-one win opportunities against slower corners. Diagnose blitz packages by checking linebacker depth, if the linebackers are crowding the line pre-snap expect man coverage behind the blitz and prioritize getting the ball out on the seam route quickly before pressure arrives.
Check the safety alignment before the snap, two deep safeties invite you to attack the seams while one deep safety means you should read the post and bender for a big play over the top.
Use the seam routes as your first read against Cover 2 since the corners sit low and the safeties have to cover too much ground to close on both seams.
Hot route the backside outside receiver into a comeback or dig if you see Cover 3 with a deep third defender sitting on top of the go route, this gives you a sure sticks conversion when the verts are covered.
Pair this play with Curls or Stick earlier in a drive so the defense starts respecting shorter routes, then hit Four Verticals off that tendency for a explosive play against zone drops that cheat up.
Best called on second or third and long when the defense is more likely to play a soft shell, and avoid it in tight red zone situations where the field is compressed and verticals lose value.
