My friend, I don't think it's a question of "If that's the QB market, then that's the QB market", because Jimmy G already set the QB market. Now he may go on to do great things in the league, but the fact remains he's woefully unproven in regards to the contract he signed--but that's the market.
The seasons Cousins has already put up should get him more than Jimmy G's contract, but I can see him settling for slightly under, depending on which team he signs with and if he feels that it will help them win a SB (which I think he's the type of QB that *can* win a Super Bowl...like a Joe Flacco, he wouldn't be *the reason* a team won it). But the QB market is insane right now, if Garoppolo got that, imagine what a bonafide Hall of Famer like Aaron Rodgers will get; or a bonafide superstar like Matt Ryan would get?
