Formations (intro)

What a formation is

A formation is the still picture: where each player lines up before the ball moves. It is not the play itself. Same shape can run, throw, or fake. Count bodies and gaps first; name the play later.

Offense: under center vs shotgun

Under center: the quarterback stands right behind the snapper, hand on the ball. Shotgun: the quarterback stands a few yards back and takes a catch-snap. Under center often looks like a run-first picture. Shotgun often looks like a pass-first picture. Either can still do both.

Offense: cluster vs spread

Cluster: skill players bunched tight, extra big bodies near the ball. Spread: receivers split wide, more space between people. Cluster crowds the middle. Spread stretches the defense sideline to sideline. Personnel still matters — see glossary and positions.

Defense: base vs extra DBs

Base: the usual mix of linemen, linebackers, and defensive backs. Extra DBs: the defense trades a big body for another defensive back when the offense spreads out. More DBs usually means the defense expects a throw. Fewer DBs, more big bodies, usually means they expect a run.

Count before the snap

Before the ball moves, count. How many big bodies near the ball? How many receivers split wide? Is the quarterback under center or in shotgun? That count is the formation. It is a hint, not a lock.

Picture vs movie

Formation is the picture. The play is the movie — first steps after the snap. A spread shotgun picture often throws; it can still hand the ball off. A clustered under-center picture often runs; it can still fake and throw. For the movie, open run vs pass.

Formation is who is where. Count before the snap. Then watch first steps to see run, pass, or both.
