It all boils down to how the new coaches view Rosen and how they view Murray. Do they feel Murray is signicantly better than Rosen? Or whether he can at least give Josh a run for his money? Or...is there some wild card QB out there that K2 likes more than Murray or Rosen?
Or...is there a non-QB draftee who knocks everyone's socks off or convinces the coaches he can help the team more than Murray?
We can speculate all we want but it's all about coaches, scouts, players and football...i.e. mainly stuff that goes on behind the scenes.
