There has been only one major player I can remember that we let just walk and that was Peppers. And we could have franchised him again.
This is the most naive post I've read in a while.
Good QBs rarely leave in free agency. We will pay him accordingly and if not we will franchise him. As someone stated above he would likely take guaranteed money rather than play for franchise money and take the risk of getting injured.
And I am not sure why people think he is so anxious to leave here. It is just that small market inferiority complex I guess.
