Say it like this
One linebacker shoots a gap. Everybody else covers behind him.
Coach detail＋
What happens
Mike blitzes the B-gap and the Safety blitzes off the edge. Both Tackles hold A, both Ends hold C/contain, Will covers B. Coverage is flexible — man or 3-deep.
Coverage behind it
Man or 3-deep. Key youth tool: a spoken "BAIL" call aborts the blitz mid-snap and reverts everyone to base coverage — show pressure pre-snap, then drop out against a quick throw.
Note
Documented weakness: a quick TE/flat pass beats it before the pressure arrives.
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.
