Sid Gillman, a Hall of Fame coach in the AFL and NFL, was a central figure in pro football’s shift from a running-oriented to a pass-centered game. An early mastermind of what became the West Coast Offense, Gillman – after coaching the Los Angeles Rams in the 1950s – became the coach and later the GM of the AFL's Chargers. With that franchise, he oversaw an innovative passing attack that helped San Diego win an AFL Championship in 1963. His high-scoring teams helped shape and boost the AFL’s image and his offensive principles were widely adopted. “The big play comes with the pass,” Gillman, who was born in Minneapolis in 1911, liked to say. Gillman was also the first coach to win a divisional title in both the NFL and the AFL, and among the first coaches to study game film to prepare for opponents.
