Brady announces retirement after 22 seasons.

The greatest NFL player of all time is calling it a career. Tom Brady is retiring after 22 years in the NFL, NFL Network Insider Ian Rapoport reported Saturday.

ESPN first reported the news.

The 44-year-old walks away after the most prolific career in football history. Brady was famously selected in the sixth round of the 2000 NFL Draft, 199th overall by the New England Patriots. Sporting an unparalleled competitive drive, the QB used that draft status to fuel his Hall of Fame career. Brady took over as the full-time starter in New England during his second NFL season, and the rest, as they say, is history.
