In football, on each play eleven men act in unison, and in each action not the individual but the corporate unit acts. When Bart Starr completed a pass for the Green Bay Packers, all the Packers could be said to share the deed; one man alone is quite helpless. When Joe Di—aggio stepped to the plate in Yankee Stadium with his unforgettable stance and fluid swing, Di—aggio stood in spotlighted solitude, and none of his teammates could act in his behalf. Football is corporate, baseball an association of individuals.
