The labels “zone” and “gap” describe broad families of run concepts. Real playbooks are more detailed, but the distinction is useful for fans.
Zone concepts
Zone runs ask offensive linemen to work areas and combinations. The running back reads how the defence moves and chooses the best available crease.
Outside zone stretches the defence horizontally. Inside zone attacks more vertically but still uses combination blocks and reads rather than one predetermined hole.
Gap concepts
Gap schemes more often create a specific point of attack and may pull a lineman across the formation. Power and counter are classic examples.
The pulling blocker can become an extra body at the point of attack, while down blocks create angles on defenders inside.
| Family | Back's job | Common visual clue |
|---|---|---|
| Zone | Read flow and choose the crease. | Line moving together in the same direction. |
| Gap | Follow a designed blocking structure. | A guard or tackle pulling across the formation. |
Viewing shortcut: if you see a lineman pull across the formation, think gap-family concept. If the whole line steps together and the back reads the flow, think zone-family concept.
