FB Belly is a power run concept out of the Pro Split Backs formation with 21 personnel on the field. The diagram shows the fullback taking a lead path into the hole with the halfback following behind him on a downhill dive path toward the strong side, with the offensive line executing down blocks and a power scheme to seal the point of attack. This is a run play, not a play-action look, and the primary read progression is patience behind the fullback lead block, reading the play side double team and kick out block before deciding to bend the run back inside or press it further outside off tackle.
Watch for a stacked box with linebackers creeping to the line pre-snap, since this signals a run blitz that can beat FB Belly if the fullback lead block gets picked off. Check safety depth before the snap, because a single high safety shell allows the defense to add an extra run defender to the box and clog the off tackle lane. Post-snap, key on the play side linebacker's gap fill: if he crashes down hard on the fullback, look for the halfback to bend the run back to the backside cutback lane. Man coverage with a Mike linebacker spying or blitzing off the edge can beat this play by disrupting the fullback's lead path before he reaches the second level. Zone defenses that flow hard to the play call side leave the backside cutback open, so track linebacker pursuit angles after the snap to decide whether to stick with the play design or cut it back.
Run this on early downs like first or second and short to medium yardage to keep defenses honest against your pass-heavy calls out of the same Pro Split Backs look. Check the box count before the snap and if you see six or more defenders stacked in the box, consider hot routing the TE to a quick out or checking to a pass instead. Use manual control on the fullback to help clear the lead block if the CPU AI misses an assignment at the point of attack. Pair this with HB Off Tackle and Power O from the same set so linebackers cannot key on one blocking scheme and get confused about gap responsibility. Against aggressive user blitzers, delay your handoff read slightly to let the fullback lead block develop fully before committing to a lane.
