H Power Toss out of Singleback F Wing Slot is a designated run play that uses a toss action to the halfback with a power blocking scheme, pulling the fullback and backside guard to lead through the hole. This is not a man or zone beater in the passing sense since there are no route options, it wins purely on gap leverage and edge speed against the defensive front. The primary read progression is the pulling fullback lead block first, then the edge defender's contain angle to decide between the designed bounce lane and cutting up inside the pullers.
Watch the play side defensive end and outside linebacker alignment pre-snap, if they are lined up tight to the tackle box the toss has a clean bounce lane to the edge. Identify fast flow linebackers who key the backfield motion instantly, since disciplined defenses that stay square and read their gaps will blow up the pulling blockers before they reach the edge. Look for a user controlled defender spying the running back or crashing down hard off the snap, as this signals the defense expects the toss and will try to string it out. Check safety depth and alignment, since a safety rotated down into the box pre-snap often means the defense has diagnosed the run tendency and will add a fitter to the edge. Post-snap, track the contain defender's angle first, if he over pursues upfield there is a natural cutback lane once the ball carrier presses the line of scrimmage.
Call this out of run heavy personnel counts against light boxes with six or fewer defenders in the box to maximize the numbers advantage at the point of attack.
Use your pre-snap read to identify if the defense is stacked with an extra linebacker or safety near the line, since a toss to the edge struggles against fast flow defenses that can pursue outside quickly.
Hot route the fullback lead blocker only if you see a clear overload on the play side edge, otherwise let the base blocking scheme develop naturally.
Pair this play with HB Power O and HB Dive from the same set to keep the defense honest on inside versus outside gap runs, forcing linebackers to hesitate on their fits.
Mix in PA Power O and PA Fl Dive after establishing H Power Toss so play action rollouts and fakes off the same power blocking action freeze linebackers who start flowing hard to the toss side.
