What happens
The Free/Strong Safety blitzes off the edge with outside leverage and contain responsibility.
Coverage behind it
Mike takes the C-gap, Will takes the B-gap and spies. Underneath defenders redistribute to 3-under with a corner rotating to the deep middle.
Coverage behind any blitz — the one rule to teach: whoever is left uncovered by the blitzer's departure rotates to fill his zone. If a Safety blitzes the edge, the other deep defender (or a rotating corner) takes the deep middle third and the underneath defenders redistribute to 3-under. If Mike blitzes an A-gap, the backside ILB or a rotating DB takes the vacated hook-curl. One rule applied consistently beats memorizing a different rotation per blitz.
