I really think da Bears have more of a chance than most folks are giving them, and I won't be surprised if they win. I'd put the odds of Green Bay winning at only 60%. That said, 60% is still 50% larger than 40% (because 40 x 1.5 = 60), so I still pick the Packers.

Packers over Bears

NY Giants over Los Angeles
Kansas City over New Orleans
Tennessee over Indianapolis 
Minnesota over Philadelphia
Cincinnati over Cleveland
Washington over Detroit 
Oakland over Jacksonville
Buffalo over Miami
Baltimore over NY Jets
Tampa Bay over San Francisco
Atlanta over San Diego
New England over Pittsburgh
Seattle over Arizona
Denver over Houston
