Tom Brady believes he may be able to continue playing for several more seasons until he's 46 or 47 years old.

"As recently as 2-3 days ago, he assured me he'd be willing to play 6-7 more years and at the level he performed," Robert Kraft said Monday at the NFL's annual meeting. "There's no one that would be happier than I, and our fan base."

Brady turns 40 on Aug. 3, and the question of how much longer he'll play has been widely discussed and analyzed.

Steve DeBerg, Warren Moon and Vinny Testaverde, all at age 44, are the oldest quarterbacks to have been on an NFL roster, according to data tracked by the Pro Football Hall of Fame. George Blanda played until he was 48, but was primarily a kicker late in his career.
