The NFL is a quarterback-driven league.
That was plainly evident in 2012, when most of the teams with poor quarterback situations found themselves at the bottom of the standings.
Not every team gets gifted with an Adrian Peterson to offset their QB shortcomings, and some of those teams will turn to the players on this list as their starter in 2013.
For some of these quarterbacks, it's not so much a matter of if as it is where. For others, the fact that they are starting at all will be one of early shockers of the 2013 campaign.
