What it is

The West Coast offense is a passing system built on short, accurate throws that work like a running game. It was made famous by Bill Walsh with the San Francisco 49ers.

In a game

Quarterbacks make quick reads and release the ball early, often on a timed rhythm. Running backs and tight ends catch many passes, and the receivers pick up yards after the catch.

More detail

The idea is to move the ball with a series of small gains instead of deep shots, so the defense cannot rest. Many modern offenses use pieces of this approach, such as slants, drag routes and quick throws to the flat.
