The Denver Broncos aren't all about passing with Peyton Manning. They've built a pretty good backfield, too.
The Broncos don't want Manning to air it out 42 times a game like he did in his last season in 2010. He missed all of last year with a weakened throwing arm, has gone through four neck surgeries, his wrenching exit from Indianapolis and the free agency frenzy that ended with him wearing orange and blue.
Coach John Fox has a beefed-up backfield to help pick up the blitz and carry the load during Manning's 2012 comeback tour.
New fullback Chris Gronkowski will lead the way for Willis McGahee, Lance Ball, rookie Ronnie Hillman and former first-round pick Knowshon Moreno, who's overcome a torn ligament in his right knee.
