Check
HEAVY
Say it like this
They moved extra big guys to one side. Find the real center and re-count your gaps from him.
What can go wrong
Defenses that align purely off "where's the tight end" get confused by tackle-over sets and misalign, giving the offense a free mismatch at the point of attack.
How we fix it
Teach every player, not just the coach, a simple pre-snap rule: count from the ball out both directions; more than 2 linemen one side of center = unbalanced, check HEAVY. Then rep the shift until it is automatic.
Coach detail＋
Front shift
"HEAVY" call plus the "NOC" rule. Strong Tackle bumps to a 5-technique-style shade, weak Tackle plays tighter (3-technique-style). Will typically gets an automatic backside edge/C-gap blitz to punish the numbers deficit on the away side.
Coverage
Free Safety slides toward the overload side for extra run support.
Gap changes vs base
- •Every gap letter is re-counted from the real (heavy-side) center, not the ball.
- •Will's contain job converts into a backside edge blitz.
