Last year, Denver struggled to stop the pass, especially against elite quarterbacks.
Since the Broncos have the toughest schedule in the NFL, it's safe to say they will be facing some elite quarterbacks.
Brian Dawkins retired, so either Rahim Moore or Quinton Carter (both young safeties) would take over. Omar Bolden, Denver's fourth-round draft pick, could see some time at cornerback, but Champ Bailey and Tracy Porter will start.
Porter was acquired from the Saints, and he is a fast, smart cornerback. He reads the quarterback well, so he can make adjustments, like when he intercepted a Peyton Manning pass in the Super Bowl and returned it for the game-clinching touchdown.
Bailey, on the other hand, is the definition of shutdown corner. He does everything a cornerback needs to do well, and he is almost guaranteed to start. Even though he is great, Denver's secondary struggled last year.
Against the likes of Tom Brady, Ben Roethlisberger, Cam Newton, Drew Brees and Matt Schaub, Denver's secondary will have to step up. Because if it doesn't, a lot of pressure will be on Peyton and the offense.
