We've already learned that 11 players can be on the field per team during a scrimmage down. However, football is different from other sports in that it allows for unlimited substitutions whenever a play ends. As a result, layers are grouped into three main categories or units:
The Defensive Unit
PRO TIP: If you're ever lost, just look at which team has the ball. The team on defense does not have the ball.
Defensive Unit Goals
- to gain possession of the ball for their team
- to prevent other team from moving closer to their end zone
- to prevent the other team from scoring points
Defensive Player Positions
We'll learn more about defensive player positions in future chapters.
