5v5 Flagonly
The quarterback aligns in shotgun, one running back aligns directly behind the quarterback on the centerline, and one receiver aligns on each side of C. This balanced single-back shell supports Lead, Trail, boot, reverse, and play-action designs. I Back (flag) differs from the single-file NFL FLAG I Formation, where C-QB-X-Y-Z all align in one centerline stack. Coaches should confirm which I formation is intended when the league or play call does not make it clear.
