Robber

Man coverage on #1 with outside leverage, funneling the receiver inside toward the robber. The CB plays differently than standard Cover 1 — instead of inside leverage with safety help deep, he uses outside leverage to drive the receiver into the trap in the middle of the field.

Mirror technique with outside leverage. The robber concept works because the CBs funnel everything inside — if a CB loses outside leverage, the receiver escapes the trap. The FS provides deep help, but the intermediate middle is the robber's domain.

Plays single-high centerfield at 18+ yards. The FS is the deep eraser — with the SS down in the robber zone, the FS is solely responsible for preventing the deep ball. Must not bite on intermediate routes or play-action. Reads the QB's eyes and breaks on deep throws.

The robber. Aligns in a two-high shell pre-snap to disguise the coverage, then drops to 8-15 yards at the snap and reads the QB's eyes. Attacks any intermediate throw — digs, crossers, curls, seams. The robber turns the middle of the field into a trap. Must be disciplined enough to not chase fakes and commit too early to one side.

Man on the RB or blitzes. With the SS playing robber, the underneath man assignments are distributed among the LBs. The WILL must be athletic enough to match backs out of the backfield.

Man on the TE or #3 receiver. The robber concept gives the MIKE some help in the intermediate middle — if the TE runs a seam or dig, the SS is sitting right there to jump the throw. The MIKE can play more aggressively knowing the robber is behind him.

Man on the strong-side TE or blitzes. If the TE releases, the SAM trails with inside leverage. If the TE blocks, the SAM can rush the passer, adding to the pressure that forces the QB into quick intermediate throws — right into the robber.
