What it is

A scramble is when a quarterback leaves the pocket to run or buy time because the pass rush is too fast and no receiver is open.

In a game

While he runs, the receivers keep moving to find open spots. The quarterback can throw on the run or turn upfield and gain yards with his legs.

More detail

A scramble is different from a designed quarterback run. It is a reaction to a breakdown, and it is one of the ways mobile quarterbacks make big plays out of bad situations.

Animated diagram

1. The pass rush is fast and the receivers are covered, so the quarterback has nowhere to throw.
2. He runs out of the pocket to the side and keeps his eyes on the field.
3. He runs for yards or throws on the move when a receiver gets open.
