2018 is the richest year for veteran free-agent quarterbacks in some time, and may also be a bit of an island, as after this season, the pickings will get slim again.
Among quality starters, only Matt Ryan, Nick Foles and Blake Bortles are slated to be free in 2019, and there is no way the Falcons will let Ryan get away and a very good chance Foles could be dealt and earn a new deal this season.
In 2020, only Aaron Rodgers is set to come free, and do you really see the Packers letting him out of town?
