One of the best articles I've ever read.
Here's a sample
"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."
