The Denver Broncos have been favorites to win the Super Bowl entering the past two offseasons. That isn't the case for the 2015-2016 NFL season.

The odds vary slightly sportsbook to sportsbook, but the Broncos' ranking of 4th in those odds stays constant, with the Seahawks ranking universally 1st, the Patriots 2nd, and the Packers 3rd. The Indianapolis Colts often come in at 5th, sometimes tied with the Broncos for 4th.
