4-4 Stack Cover 3

Classic 8-in-the-box youth/HS run defense — 4 down linemen + 4 linebackers (Will, Mike, Buck, Sam) + 3 DBs (2 corners, 1 deep safety in Cover 3). Two ILBs stack directly behind the DTs; two OLBs play just outside the DEs. Heavy run support; vulnerable to spread passing because there are only 3 DBs to cover 4-5 receivers.
