FB Dive Strong

Breakdown

FB Dive Strong is a downhill run play out of the I Form Pro set with 21 personnel, sending the fullback directly through the strong side of the line right behind the quarterback's handoff. The diagram shows a tight, compact blocking surface with no receivers running routes, meaning this is a pure interior run play with the offensive line and TE working double teams and combo blocks up front to seal the strong side gap. The primary read is the fullback hitting the hole quickly off the mesh point, reading the initial push from the guard and tackle to decide between the A gap and B gap on the strong side.

Defensive Reads

Look for base 4-3 or 3-4 fronts with linebackers playing downhill, this play struggles against stacked eight man fronts or heavy blitz packages sent right at the strong side gap. Pre-snap, check if the strong side defensive end or outside linebacker is crashing hard, since that alignment can blow up the dive before it develops. Watch for a Mike linebacker sitting tight in the box, if he reads dive quickly and fills the strong side gap this play has no answer with such minimal blocking numbers. Man coverage or zone coverage on the back end does not matter much since there are no routes, so focus entirely on the front seven's gap discipline. If the defense shows a heavy blitz look with extra defenders crashing downhill pre-snap, consider an audible since this play has no built in answer against pressure.

Usage Tips

Run this on early downs like first and second and short to medium yardage when the defense is not stacked with extra defensive backs. Check the defensive line spacing pre-snap, if you see two down linemen shaded away from the strong side call, this play hits fast for positive yardage. Use this as a change of pace after running HB Dive or Inside Zone to keep linebackers guessing on which back gets the ball. User the fullback immediately after the snap and trust your line, patience at the mesh point kills the timing of this quick hitter. Pair this with FB Dive Fake HB or PA Power O later in a series to freeze linebackers who start keying the fullback dive too aggressively.
