Of course with 3 games to play a lot can happen to change things but it could be a strong market for FA QB's which could make the negotiations tough for both sides. Cousins, Garropalo, Taylor, Bradford, Keenum, Bridgewater, Cutler, Brees.
On the other hand some likely won't hit the market but there are options for teams unwilling to (over)commit before FA. Plus with all the coaches moving and a potential strong rookie class "Bridge" QB's might be the popular types. New coaches/FO might prefer a rookie 'Franchise QB' on the cheap with a middle thirties vet to buy time for the rookie.
