The greatest quarterback of all time is moving on. Tom Brady has announced on social media that he’s decided to leave the New England Patriots and explore his options in free agency.

Brady has spent his entire 20-year career in Foxborough. He’ll be playing on a new team for the first time at 43 years old.

Where will Brady end up? That remains uncertain. The quarterback can officially sign elsewhere Wednesday, and he has several suitors.

The Tampa Bay Buccaneers have emerged as the top contender to sign Brady. According to NFL Network’s Ian Rapoport, Tampa Bay has offered Brady at least $30 million per year.

The Los Angeles Chargers have been linked to Brady for months. The team has reportedly made Brady a strong offer in free agency.

Tampa Bay didn’t re-sign Jameis Winston, who was their starting quarterback for each of the last five years. Los Angeles parted ways with Philip Rivers early in the offseason.

The Tennessee Titans were once thought to be a possible destination for the six-time Super Bowl champion. Tennessee took themselves out of the Tom Brady Sweepstakes when they signed Ryan Tannehill to a four-year contract.
