A scene like this plays out eight times a year in Green Bay. The fans will crate their parties and surge toward entry portals, and they will look very much like a football team, sheathed in their XXXL gamewear models designed for 320-pound men to wear in actual football combat or for far smaller people to wear over five layers of lycra, fleece and down. The scene is almost gladiatorial; just as the players funnel down a narrow tunnel and emerge to the roar of their fans, those same fans push hurriedly into the coliseum in the final moments before kickoff, one with the event, dressed to kill. But understand: This scene is striking not because it is unusual but because it is commonplace.
