Bleacher Report's own Dan Levy, Josh Zerkle, Matt Miller and yours truly take a crack at the best- and worse-case scenarios for the reigning AFC West champs, the Denver Broncos. 

Obviously, a lot has changed on the offensive side of the ball, with the free-agent signing of Peyton Manning being the headline of the offseason. Along with Manning comes a new offense and a few new parts—like tight ends Jacob Tamme and Joel Dreessen—to go along with the talent that was already on hand, like wide receiver Demaryius Thomas and the underrated Eric Decker.  

The Broncos will have a few new parts on defense as well, starting with the man coordinating them: former Jaguars head coach Jack De Rio. Obviously, he'll be counting on Von Miller and Elvis Dumervil to get to the quarterback and on Champ Bailey and newcomer Tracy Porter to stop the ball from getting to receivers. 

With all of that said, this team will go as far as Manning takes it, no matter what John Fox and company do. The sky is the limit if Manning is healthy and even 80 percent of the quarterback he used to be. But don't be surprised if defensive coordinators go after the four-time league MVP early and often, starting on opening night against Dick LeBeau and the Pittsburgh Steelers.

Of course, all it will take is one classic quick-strike touchdown against the blitz for folks to say, "Manning is back!"

Broncos fans hope that is the case.
