You do not need every position name to enjoy a game. You do need a rough map: who is trying to move the ball, who is trying to flatten that plan, and why 22 people keep changing.
The offence, in plain language
- Quarterback (QB): the organiser. Takes the snap, then hands off, runs, or throws.
- Running back (RB): takes hand-offs and short passes. Often the person bursting through the middle.
- Wide receivers (WR): the sprinters out wide, trying to get open for a catch.
- Tight end (TE): a hybrid: blocks like a lineman, catches like a receiver.
- Offensive line (OL): five big people whose job is mostly thankless: protect the QB and open holes for runners.
Most plays are either a run (the ball is carried) or a pass (it is thrown). Play-action is a bit of theatre: the QB pretends to hand it off, then throws, hoping the defence bites.
The defence
- Defensive line (DL): try to shove the offensive line backwards, sack the QB, or stuff the run.
- Linebackers (LB): the all-rounders behind the line. Tackle, cover, blitz.
- Cornerbacks (CB): mark the wide receivers.
- Safeties (S): the last line, deeper down the field.
Why they keep changing players
Because the jobs are different. A 140kg lineman is not asked to chase a receiver for 40 yards. A receiver is not asked to stop a running back in a phone box. Coaches swap packages the way a cricket captain changes the field: more tall people if they expect a pass, more heavy people if they expect a run.
- Sack
- Tackling the quarterback behind the line of scrimmage, before they throw or hand the ball off.
- Blitz
- Sending extra defenders after the quarterback, gambling that you hit them before they find a receiver.
- Coverage
- How the defence marks receivers: man-to-man, or a zone where each defender patrols an area.
