Football Fundamentals
How Downs Work
Football gives the offense four downs to gain ten yards, score, or choose how to surrender possession.
Field Position
Field position describes where the ball is and how that location changes risk, play selection, and scoring choices.
Football Positions Explained
Every snap is eleven players with jobs: throw, catch, block, rush, cover, or tackle.
Offense
Offensive Formations
A formation places eligible receivers and blockers before the snap to create spacing, leverage, and assignment clues.
Personnel Groups
Personnel groups identify the types of skill players on the field and shape what formations and concepts are credible.
Running Plays
Running concepts coordinate blocking angles and a ball carrier's read to attack defined gaps or stretch the defense.
Passing Concepts
Passing concepts combine routes so one defender or coverage rule must account for competing threats.
Pass Protection
Pass protection assigns blockers to preserve a pocket and account for likely rushers long enough for routes to develop.
Defense
Defensive Fronts
A defensive front aligns box defenders to control gaps, influence blocking combinations, and generate pressure.
Man Coverage and Zone Coverage
Man defenders track particular receivers, while zone defenders protect space and distribute routes by rules.
Coverage Families
Coverage families describe how defenders divide deep space, underneath zones, and receiver matchups after the snap.
