How many good QBs hit FA these days?
Manning did but that was purly down to a circumstances that come around once in a blue moon(Aging QB with career in doubt,team has number one pick with one of the greatest QB prospects ever coming out that year)

QBs dont sit and develop these days,most start pretty quickly and Luck,Wilson have had good success really early. RG3 first year was impressive,Tannehill gets better each year. Id rather take a shot on any of them in the draft,especially when you consider what average QBs like Cutler,Flacco cost and eeven they do not make FA.

The biggest FA QBs in the past few years with salary (years/overall/guarantee)

Ryan Fitzpatrick 2/6.5/1.75
Alex Smith 3 /$27/9ml
Chase Daniel 3/10/4.8
Matt Flynn 3/19/0

Non of them will win you anything
