One of the best articles I've ever read.

"Coryell and Walsh took their lead from Gillman and further expanded the thought process of football. They were creative and imaginative, seeing the pass as a means of limitless possibility and choreographed beauty. It was Coryell who first recognized the tremendous value of a tight end with Kellen Winslow, who could align anywhere in the formation and essentially be deployed as another wide receiver. Walsh saw offensive football as a wide palette of strategy and tactics, more of an art form than a game of brute strength and physical will. He featured (and mastered) a controlled midrange passing game, primarily working from the inside out, both celebrating and expanding one of Gillman's core beliefs: If you control the middle of the field with the passing game, you can attack and win on the outside."
