Chapter 1: 1. Field, Roles, and Game Flow

The Field and Basic Goal

American football is played on a 100-yard field with end zones at both ends.

  • Offense tries to score points
  • Defense tries to stop them and gain the ball

Teams score by:

  • Touchdowns (reaching the end zone)
  • Kicks through the uprights

Games are split into 4 quarters, with a halftime break.

> Big idea: Move the ball downfield and finish drives with points.

1. Field, Roles, and Game Flow

Offense vs. Defense vs. Special Teams

Each side has 11 players on the field.

Offense

  • Quarterback (QB)
  • Running backs, receivers, linemen

Defense

  • Linemen, linebackers, defensive backs

Special Teams

  • Handle kickoffs, punts, field goals, extra points

> Different units come on and off depending on the situation.

Downs and Yardage

The offense has 4 downs (plays) to gain 10 yards.

  • Gain 10+ yards → 1st down (new set of 4 downs)
  • Fail after 3rd down → usually punt on 4th
  • Close to scoring → may try field goal on 4th

Chains on the sideline mark the line to gain.

> Managing downs is core strategy.

Game Clock Basics

NFL and most high school games:

  • 4 quarters, usually 12–15 minutes
  • Clock stops for incomplete passes, going out of bounds, penalties, timeouts, and some first downs

Teams have timeouts each half to stop the clock or adjust.

> Good clock management can win or lose close games.
