Most people believed Tom Brady would be a lifelong member of the New England Patriots.
It's still possible that will be the case for the 42-year-old quarterback. But with Brady set to explore the free-agent market, there's a chance that the six-time Super Bowl champion will head to a new organization.
With the start of NFL free agency coming soon, Brady isn't the only experienced quarterback without a team; Drew Brees, Philip Rivers and Dak Prescott are among the players who don't yet have contracts for the 2020 season.
