Dynasties are over in the NFL. You need Marshawn to be Marshawn for the next three years and that simply isn't happening, you need Percy Harvin to be what he was tonight for the next three years, that's not happening. You need 31 NFL teams not adjusting to a good, but not great, Super Bowl champ ... that's not happening. Congrats for a great game, Seattle, but one game doesn't make you a great team or a dynasty. You feel like Tampa Bay, a fine one-year Super Bowl champ, but hardly a guaranteed dynasty.
