Tom Brady is due to be a free agent when the NFL league year starts. Ian Rapoport mentioned the Tennessee Titans as one of the teams that will pursue signing Brady. The other two teams he mentioned were the Las Vegas Raiders and the San Francisco 49ers. As for the Titans, I cannot see that being a road they go down.
The Titans were rumored to be in the mix when Brady left the Patriots. The obvious connection is to Mike Vrabel. Vrabel and Brady played together in New England and are very good friends.
