5. Denver Broncos (7)
After winning the Super Bowl thanks to their stellar defense, the Denver Broncos could be even more dangerous in 2016 thanks to an upgrade on offense.
As great as Peyton Manning was throughout his career, the future Hall of Famer only threw nine touchdowns in 10 games last year and now it looks like the Broncos will rely on Trevor Siemian to run the offense. Siemian may not have any starting experience heading into his second season, but the former Northwestern standout has shown potential in the preseason with a canon of an arm.
However, just because Siemian’s capable of throwing the deep ball doesn’t mean his accuracy has been on point. Once he gains more experience as the starter, Siemian should be comfortable running the offense in no time–especially with all of the weapons in the passing game.
