Counter Y

Pre-snap, check linebacker depth and alignment: stacked or crashing linebackers can be gashed by the counter action if they overcommit to the initial flow. Look for safety rotation into the box, which signals run support and can clog the cutback lane. Post-snap, key the play side defensive end and outside linebacker: if they stay disciplined and read the counter step rather than crash upfield, they can blow up the pulling blockers. User controlled defenders sitting in the hole or flowing hard to the play side call are the biggest threat to this run, so a patient cutback is essential when the backside is left unblocked. Base 4-3 and 3-4 fronts without extra edge defenders are the most vulnerable, while heavy blitz packages that send extra bodies through the backside gap can blow this play up before the pullers get set.
