I'm supposed to be grading the quarterback unit, but there's only one that has produced points, leadership and wins for the Broncos: Peyton Manning.
Peyton Manning has been better than expected. After starting out slow in Week 1, Manning is second in passing yards (1,808), passer rating (105.0) and touchdowns (14). Manning also made history when he was the first quarterback to pass for 300 yards and three touchdowns while completing 70 percent of his passes in three straight weeks.
What makes this even more impressive is that this is all under a new team, new coaches and new fans. He is also improving the team as a whole and making his teammates play better.
If something happens to Manning, the Broncos are in trouble at the quarterback position. Backup quarterback, Brock Osweiler, is a rookie and has very little experience. John Fox does keep him prepared by having him study the game plan and giving reps during the week, but he hasn't seen any game experience.
Caleb Hanie is the third-string quarterback, but hasn't shown much productivity over his short career in Chicago and Denver.
