The Steelers weak spots were exploited by one of the true defensive genious' of the game, Belechick. And at this point in the life of Tom Brady it seems like the only one that can stop him might be himself. Whether that happens or not is a wait and see situation.
The cheating thing has been blown out of proportion. Every team in sports has been spending extra time trying to find ways of getting inside information on it's opponents. Patriots got caught, others haven't.
Tom Brady could have signed for more money on the open market a year or so ago. He and others have taken a team spitit and chemistry approach to keep the unity and neucleus of team intact as well as attracting top players to keep greatness. Unseen loyality not common anymore.
The Steelers could have remained dominant had they not lost a few key players to free agency and greed. You can't blame someone for wanting more money but there comes a time when one recognizes that fame will last much longer than money. Brady has figured that out. Favre has also.
