At the moment I think New Orleans Saints is the clear favourite in NFC. In AFC I have Kansas City Chiefs, New England Patriots and Pittsburgh Steelers. Chiefs is my favorite, if they can keep the first seed. Patriots have some injuries, but when they are back, Patriots look strong. You never know with Steelers, one week they score 50 points, the next they can't score in three quarters. An honorable mention to L.A. Chargers. They have a great season so far, but it's Chargers we are talking about. They are the champions of losing a game in the last minutes.
So my Super Bowl would be N.O. Saints vs K.C. Chiefs. Saints winning the SB with 11 points. The score, (a guess of course), 42-31 to Saints.
