Vote: Which team has best shot at dethroning Patriots?

The defending champion New England Patriots head into the season with far and away the best chances of winning Super Bowl LII, according to ESPN's Football Power Index (32.4 percent chance).

A Super Bowl repeat is far from a slam dunk, however. ESPN has tabbed five teams -- the Atlanta Falcons, Green Bay Packers, Oakland Raiders, Pittsburgh Steelers and Seattle Seahawks -- as having the best chances of dethroning the champs. Which among them do you see as having the best shot?

The Patriots open defense of their championship on Thursday night, hosting the Kansas City Chiefs in the NFL season kickoff.
