Bill Walsh, one of the greatest minds in the history of football has passed. He changed the way the game was played, and left behind a legacy of coaches from his "family tree" that is unrivaled. RIP Bill Walsh.

I was surprised to hear he was 75. I always thought of him as younger than that.
His "West Coast" offense was often duplicated, rarely equaled under his tutelage.
A great coach.
