GAP 8

What is GAP 8?

GAP 8 meaning old defensive formation in which every gap had a defender in it; not viable now because defense cannot rely on offense to be in a full-house backfield formation with two tight ends like in the old days; also, in this era of passing to all five eligible receivers, it is unsound to rush more than five men without switching to man pass coverage; the five man pass coverage defenders must align on their men or in the defensive backfield and not in a gap See my book Gap-Air-Mirror Defense for Youth Football: The Modern, Flexible Version of the Gap-8 and 10-1 Defenses.
