Maybe not Bark...have you seen the crop of UFA QB's scheduled to hit the market in 2016? Yikes!
There's:
Sam Bradford
Drew Stanton
Chad Henne
Matt Moore
Luke McCown
Matt Schaub
Matt Cassel
Charlie Whitehurst
Matt Flynn
Brandon Weedon
Just to name a few. I left off names that either won't be leaving their team (like: Ryan Fitzpatrick, Brock Osweiler and Kirk Cousins) or due to age aren't really an option for Dallas in 2016 (Matt Hasslebeck and Michael Vick) or just aren't really viable options (Case Keenum, Chase Daniels, T.J. Yates, Jimmy Clausen, Dan Orlovsky, Joe Webb, Thaddeus Lewis, et al).
Robert Griffin starts to look pretty appealing when one looks at what could be backing up #9 in 2016. I shudder to think what the team would do next season with an inadequate backup and a #4 pick in the draft "future franchise QB" who has to be thrust into games if #9 goes down for multiple games.
