Counter Y is a power run play out of Shotgun Y Off Trips Stack that pulls the backside guard (and sometimes a fullback or wing) to lead through the hole for the ballcarrier. The blocking scheme relies on the play side double team to create a wall while the puller kicks out the edge defender, giving the runner a designed misdirection path. This is a run play, not a pass concept, so the primary read progression is patience: press the initial misdirection step, locate the pulling blocker, then decide between following the puller through the designed hole or bouncing outside if the edge is sealed.
Look for light boxes with five or fewer defenders before the snap, this is the green light for Counter Y. Identify overaggressive linebackers flowing hard to the play call side, since the counter action is designed to punish exactly that trigger. Watch the edge defender on the play side, if he sits home and does not chase the initial flow, the kick out block may not seal him cleanly. Against man coverage shells with safeties rotated to the trips stack side, the box is often thinner, making this a favorable run look. User linebacker lurks that stay square in the hole can blow up the cutback lane, so respect a spy or a lurking Mike linebacker holding gap discipline. Stacked fronts or heavy blitz packages with extra defenders crashing downhill can beat this play before the puller arrives, so avoid calling it into obvious run blitz alignments.
Run this out of second and short or first down to keep defenses honest against the trips stack look.
Check the box count pre-snap, if the defense has six or more in the box, consider audibling to Curls or Deep Stick instead to punish the aggressive front.
Use manual motion or a hot route shift on the stack receiver to draw a linebacker out of the box and create a numbers advantage for the counter action.
Sell the misdirection with the analog stick, do not rush the cutback step or you will kill the blocking scheme's timing.
Pair this play with Deep Stick on early downs to keep linebackers reading run fits honestly, then hit the seam once they start crashing down on Counter Y tendencies.
