Not only does the computer say Green Bay and New England are favorites in their conference, it puts their chances of getting to the Superbowl at both over 50%. This is in large part due to having first round byes and home field advantage through the playoffs. The Packers even have a 35% chance of winning it all to just over 25% for the Patriots.
As you'd expect, the other teams with first round byes are the second choices in each conference, Baltimore having a nearly 27% chance of getting to the Superbowl and the 49ers, almost 23%. Interestingly, because of the potential matchups in the Superbowl, the 49ers have a better chance of winning it all than Baltimore.
Who has the longest shot? While Denver is the lowest rated team in the playoffs, because they get a home game, albeit against Pittsburgh, they beat out Cincinnati, both with less than a 1% chance of winning the Superbowl and under a 2% chance of getting there.
