Many teams don’t have much of a difference between starter and backup. Heck, they are battling for jobs in the preseason in some of those cases. I purposely left those out. Instead I include situations that there is a clear-cut starter, but if he went down, they have a capable, proven backup that could keep the ship from going down…at least for a few weeks.
Dallas- Kyle Orton
Indianapolis- Matt Hasselbeck
Minnesota- Matt Cassel
Miami- Matt Moore
Detroit- Shaun Hill
Pittsburgh- Bruce Gradkowski
Yes, I think teams like New England, Denver, and Green Bay would be screwed, but not sure their backups are as bad as what these teams have.
Atlanta- Dominique Davis, Sean Renfree
Oakland- Terrelle Pryor, Matt McGloin, Tyler Wilson
Chicago- Josh McCown, Matt Blanchard
New Orleans- Luke McCown, Seneca Wallace
Arizona- Drew Stanton, Ryan Lindley
