Trail Shake out of Shotgun Trey Open Offset features two outside receivers running vertical seams to stretch the deep zone while the two inside receivers work a shake concept underneath, with one runner crossing left on a deep in and the other cutting back right on a shallow drag against the grain. This combination attacks zone defenders by clearing the middle of the field vertically and then settling zone beaters into the vacated space, though the crossing shake routes also create natural rub separation versus man coverage. The primary read progression starts with the shake combo underneath, working the crossing routes for the leverage mismatch, then climbs to the vertical seam or go route on the boundary if the underneath defenders sink or the safety bites down.
Watch linebacker depth at the snap since shallow zone drops signal a Cover 3 or Cover 4 shell that this play is designed to shake underneath. Check safety alignment before the snap, two high safeties usually mean softer underneath zones and open crossing lanes for the shake routes. Post snap, track any user controlled linebacker sitting in the shallow crossing lane since a well timed lurk can jump the underneath routes and bait a turnover. This play struggles against aggressive man coverage with a deep safety help over the top, since the crossers get picked off cleanly at the line without natural rub protection. Identify blitz packages that send extra rushers off the edge, since the quarterback needs time to work through the shake read before climbing to the vertical option.
Look for the shake crossers first since they settle right into the throwing lanes vacated by linebackers dropping into zone, giving you a quick rhythm throw before the pocket collapses.
Use this on second and medium to third and short since the underneath crossers create easy chain movers if the vertical routes are covered.
If the defense shows two high safeties pre snap, expect softer underneath coverage and prioritize the shake routes immediately off the snap.
Pair this play with Four Verticals or Y Corner KO from the same set to keep the defense honest on the outside seams before dialing this back in as the counter.
Motion or shift into this formation to get a pre snap read on man versus zone, then hot route the shallow crosser into a quick out if you see man coverage rolled hard to that side.
