I agree with DagoTom about New Orleans. I think there's a real hope among those at NFL headquarters that the Saints make the Super Bowl.
As for the Chargers, I don't think those same people care as much.
I definately think the lion's share of the media, the Stuart Scotts, Deion Sanders,Shannon Sharpes and Pete Priscos of the world, definately want the Chargers to win. They've got LT who is obvioulsy an exciting player to watch, they've got the sad sack coach everyone seems to like but who always chokes it off when it matters most, and one of the most dynamic defensive players in the league. The Chargers are a lot more "sexy" than the Pats and most of these guys have resented the Patriots success since Day 1 of this recent run so it's not surprising.
THe only problem with the hype I really have is with Merriman. He's a cheater who felt like he was above the rules, and by extension, above the game itself. He's basically been given a pass for what happened.
