"Each
player is an extension of his teammates. When Jerry Rice catches a ball, he is
an extension of several players – those who are blocking the pass rushers, the
receivers who are precisely coordinating their routes with his and the
quarterback who is taking a hit after throwing the ball. When Roger Craig broke
through with a big run, it embodied the fierce execution of the offensive line,
the timing of their blocks and the execution of the down-field blocks by the
receivers."
From "Finding The Winning Edge" by Bill Walsh
