What it is

Pass protection is the blocking that keeps pass rushers away from the quarterback, so he has time to throw. The offensive linemen and backs work together.

In a game

The line forms a cup around the quarterback, called the pocket. The linemen block the rushers, and the running backs pick up blitzing linebackers.

More detail

Good protection depends on communication. The center calls out who blocks whom, based on the defense’s alignment, and a blitz from an unexpected place can break it.
