One of the most fascinating free-agent moves. Peyton Manning missed the 2011 season with a neck injury. The Indianapolis Colts decided it was time to move and Manning moved on to the Mile High City. He won Super Bowl 50 as a Bronco and was heroic in coming off the bench in doing so in 2015. Manning started 57 games as a Bronco and was a sterling 45-12.
