As far as I can remember, something like this has never happened.
Tom Brady is a free agent. Drew Brees is a free agent. Philip Rivers is a free agent. Jameis Winston is a free agent. Ryan Tannehill is a free agent. Marcus Mariota is a free agent. Teddy Bridgewater is a free agent.
A.J. McCarron is a free agent. Remember when McCarron was about to enter free agency a few years ago and all the buzz was how he could get Brock Osweiler money?
