Peyton Manning is struggling but the Denver Broncos' odds of winning the Super Bowl remain better with him at quarterback than Brock Osweiler.

Prediction Machine ran 50,000 simulations with Manning and the Broncos win the Super Bowl 10.8 percent of the time, which is the fourth best of any team in the NFL. Denver would win the Super Bowl 9.6 percent of the time with Osweiler as the difference between the two is less than a field goal per game.

The Broncos would be Super Bowl favorites with Tom Brady, Aaron Rodgers, Ben Roethlisberger, Philip Rivers, Drew Brees or Tony Romo starting. Denver would also improve their standing, though not favorites, if they had Andy Dalton, Carson Palmer, Matt Ryan, Russell Wilson, Andrew Luck, Eli Manning or Cam Newton.
