This again? I don't get where this idea comes from. Who is this "proven NFL QB" that's available(or will be)?
I am definitely in the replace JB camp, but I just don't see any proven NFL QBs that are available. There maybe someone unsuspected come free, but IMO none of the QBs who are generally considered available or likely to be this off season are worth going after. Bridgewater, Dalton. Foles, Newton ... A couple are slightly better than JB, but not enough of an improvement to make it worth the investment. Might as well just keep JB for the last year of his deal while you roll the dice on a rookie if those are the "proven NFL QB" choices.
