Rookie quarterbacks most likely to see the field in 2013
6. Landry Jones (PIT): Ben Roethlisberger's style of play leaves him vulnerable to minor injuries - he hasn't played 16 games in a season since 2008 (though he only missed games in 2010 due to suspension). Jones would have to beat out journeyman Bruce Gradkowski to earn a start if Big Ben goes down.
7. Brad Sorensen (SD): Philip Rivers is 31-years-old, took a beating last year, and will likely play behind another porous offensive line in 2013. With all the shots he'll be taking, there is an increased chance he could suffer an injury. Sorensen would have to beat out Charlie Whitehurst and his 64.6 career quarterback rating to earn the backup job.
8. Ryan Nassib (NYG): Although I see Nassib as the fifth best quarterback in his draft class, Eli Manning has made 146 consecutive starts - the third longest streak ever. The Giants traded up to grab Nassib, which shows that they are high on him and will give him a legitimate shot to beat out David Carr for the backup job.
9. Sean Renfree (ATL): Matt Ryan has started all but two games during his five years in the league. It's unlikely any quarterback will see the field other than Ryan, but Renfree is a long-shot possibility if Ryan gets hurt. Dominique Davis is penciled in as Ryan's backup, and the organization is reportedly pretty high on the 2012 undrafted free agent. However, NFL Network's Mike Mayock picked Renfree as his sleeper quarterback of the draft, and I've heard multiple people say he could be a starter down the road, so I'd give Renfree an incredibly slight chance to win backup duties.
10. Zac Dysert (DEN): Though I expect him to remain healthy all season, Peyton Manning is 37-years-old with a history of neck issues. Dysert would have to beat out last year's 57th overall pick Brock Osweiler for backup duties.
11. BJ Daniels (SF): Will Colin Kaepernick be able to stay healthy through a full season of running rampant and taking shots from opponents? If Kaepernick does get hurt, Daniels would need one or two more injuries before he'd get a chance to see the field.
