Sam Mike 3 Press is a Cover 3 zone blitz look out of the Nickel 2-4 Odd set with press alignment on both outside corners. The diagram shows both cornerbacks jamming at the line and sinking into deep thirds, the safety in the middle rotating into a deep third as well, while the underneath zone defenders (Sam and Mike linebackers along with the nickel and remaining backer) flow into short zone drops. Four defenders show blitz arrows crashing off the edge and through interior gaps, signaling this is a five-man pressure package with three deep defenders holding the top of the coverage, making it a zone-based blitz beater against quick passing concepts.
Pre-snap, check for trips or bunch formations that can create natural picks against the press corners and force early leverage decisions. Post-snap, watch the middle field safety rotate into the deep third and use that defender to rob any deep crossing routes. Identify if the offense is running hot routes or sight adjustments against the blitz, since the four rushers can be beaten by quick screens if unblocked gaps are not accounted for. This beats teams that rely on timing based quick outs and slants because the press disrupts the release, but it is vulnerable to double moves if the corner loses the jam. Watch running back or tight end check downs into the vacated underneath zones created by the blitzing linebackers, since that is the primary hole in the coverage shell.
Call this when you diagnose a shotgun spread or empty formation that likes to throw quick game, since the press corners disrupt route timing at the snap.
Use the four-man pressure to force a fast throw and rely on the three deep defenders to bracket verticals down the field.
Combine this with Sam Mike 1 in your call sheet so offenses cannot key blitz direction based on man versus zone shells post-snap.
Best on third and medium to third and long where the extra rusher and press coverage combine to disrupt sticks and slant routes.
Avoid calling this against heavy play-action rollout teams since the aggressive underneath blitz can be exploited by boot action to the flat.
