Only eleven of your roster take the field for any given snap, and whether they're your offense or your defense changes every position label — build the specific eleven you're starting, not a generic depth chart.
The lineup maker supports offensive sets (I-Formation, Shotgun, Singleback, Pistol) and defensive fronts (4-3, 3-4, Nickel), so you can represent the starting eleven for any offensive or defensive unit across the 120 x 53.3 yard field.
