Take a look at the NFL Futures odds from The Greek (found here). Since they're collecting roughly the same juice on the Super Bowl and both conference markets (about 16%), we can use each team's Super Bowl and conference odds to calculate their approximate chances--in The Greek's opinion--of winning the Super Bowl should they get there:
I doubt any of Olympic Sports' oddsmakers actually think that New England and Tampa Bay are the best the NFL has to offer, but talk about having no clear-cut favorite. The number 1 seeds from both conferences are dogs in the big game, and if Atlanta wins the NFC South--which they have a downright decent chance to do--both 2 seeds will be dogs as well!
Hey, at least they correctly identified the weakest participant in the tournament.
