What team(s) besides the NY Giants are a good representative for the NFC in the Superbowl?

I am not asking for "who's your favorite team". I need real answers from real NFL football fans. Please list team or teams and your reason why. I don't see anyone from the NFC north or east (besides NY) being a threat. NFC South? Tampa or Carolina? NFC West? The Cards. These teams don't seem strong enough to represent the NFC.
