Manning recently retired from the game after the 2019 season, with 2 Super Bowl wins and Super Bowl MVP Awards (all with the Giants). One of those wins was against Brady during his tenure with the New England Patriots.
He explained to the New York Post that he was a little stunned about the development.
Tom Brady stunned the sports world by leaving the Patriots and signing with the Tampa Bay Buccaneers on March 20, officially ending a 20-year run with the team that drafted him. His move was met with both praise and criticism from fans and media alike.
