Sluggo Seam attacks vertically out of Y Trips Offset Wk with a five man route concept designed to stress man coverage on the outside. The backside X runs a sluggo (slant and go) to clear the corner deep, the trips side has a seam route from the slot climbing straight up the hash while the outside trips receiver runs a corner route and the innermost trips man runs a short drag underneath to hold linebackers. Your primary read starts with the seam sitting down against zone or breaking open against man, then progresses to the sluggo on the backside if the corner bites on the double move.
Watch the corner over the sluggo receiver at the snap, if he presses hard and jumps the initial slant fake the go route behind him is wide open. Read the middle linebacker depth pre-snap, if he is sitting shallow the seam route will have a clean throwing lane straight up the hash. Identify single high versus two high safety shells before the snap, single high leaves the seam vulnerable while two high can rob it with the deep safety sitting in the middle of the field. Look for a user controlled defender lurking in the shallow drag area, that is the most common spot for a jumped route and a pick six against this concept. Cover 3 with a hard blitz shuts this down fastest since it removes the time needed for the sluggo to develop, so protect the pocket and check the drag as a quick answer against pressure.
Check the safety alignment before the snap, single high shells give the seam room to work between the hashes while two high shells force you to lean on the sluggo double move to beat the corner.
Use the sluggo as your alert route versus man coverage teams that play aggressive press, it is designed to bait the corner into jumping the initial slant fake.
Hot route the drag into a quick out if you see a linebacker sitting in the shallow zone, it gives you a built in checkdown against zone drops.
Pair this with Four Verticals and Stick from the same set so defenses cannot key on route distribution out of Y Trips Offset Wk, the seam and drag look identical at the snap for the first two steps.
Best called on second and long or third and medium when defenses are more willing to play man coverage and blitz off the edge, since the sluggo needs time to develop.
