The NFC was weak this year, but I don't see people hating on the Saints. I don't see how you can call them out when recent weak teams (Cards, Bears, Giants) have made the SB and even won it. The Falcons were top ten in offense and defense. The '06 Bears played in a rather weak NFC and got to the SB with Rex Grossman...
How were those the same Falcon teams? Martin only played in '98 and Anderson tore his ACL in '99 and only played 2 games.
Maybe they didn't start EVERY single player every game over those 3 years, but they were still a one year wonder....and even a Falcons fan can't deny that. Atlanta is easily a bottom dweller when it comes to franchise's success during the Super Bowl era.
There is no justification for putting the Browns on that level. Unless, by 'franchise,' you mean the new incarnation of the Browns that replaced our old franchise (which went on to do great things in Baltimore) in '99.
Cleveland is one of the most storied franchises in the NFL.
