There's a wonderful old clip of Bill Parcells, back when he was coaching the New York Giants, where he shouts that his team is too dumb to be any good. Parcells has always been ahead of the curve. Football is a game of grit and power, but with each season it's becoming more like chess played on grass. Winning teams depend on smart players who can grasp complex systems, stay focused through a long season, and cope with nagging injuries. (Yes, playing through pain has a mental component: It's all about concentration.) So think of what follows as the flip side to those classic all-Madden teams stacked with smashmouth grunts.
