95 Willie out of Weak I is a power run designed to hit off tackle to the strong side, using the fullback as the lead blocker to seal the point of attack. The diagram shows the tight end and playside tackle combo blocking down while the fullback (red route) kicks out or leads through the hole, with the backside blockers pulling to create a wall for the running back to follow. This is a downhill power scheme, not a play-action or RPO look, and the primary read is to press the fullback's lead block and pick the crease off tackle, bending it back inside if the edge defender squeezes down.
Pre-snap, check the strength of the defensive front. If the defense is shifted toward the strong side with an extra defender near the tight end, the lead block will have a tougher time creating a clean lane. Look at linebacker depth. Linebackers sitting tight to the line at four yards or less can beat the fullback to the hole and blow up the play before it develops. Post-snap, key the playside defensive end and outside linebacker. If they crash down hard on the down blocks, the play should bounce outside off the fullback's adjusted path. Watch for a user-controlled defender flowing hard downhill from the second level, since that is the most common way this run gets stopped for a loss. This play struggles against gap-sound eight-man fronts and Cover 0 run blitzes, but it beats light boxes and defenses playing off coverage on the back end that are not stacked to defend the run.
Run this on early downs like first and ten or second and short to stay ahead of the chains and keep defenses honest against your play-action shots later in the set.
Check the box count before the snap. If the defense has stacked the box with an extra run defender near the strong side, consider bailing to PA Waggle or TE Flat off the same formation to punish overpursuit.
Use the fullback lead block as your primary aiming point. Manually control the running back after the handoff and press the hole hard before making your cut, since the power scheme wants patience, not east-west movement.
Pair this with Counter F and H Counter Strg in your play calling script so the defense cannot sit on one blocking scheme, since all three attack downhill but from different angles.
Against aggressive linebacker blitzes, this play can hit fast because the double team up front absorbs the extra rusher, so do not hesitate to hand it off even when you see extra defenders creeping toward the line.
