Tom Brady played in the NFL for 23 years, and while he may be retired now, he knows very well what it takes to succeed in pro football.
TB12 is a seven-time Super Bowl champion and is arguably the greatest NFL player of all time. Brady, who was selected 199th overall by the New England Patriots in the 2000 draft, is also a three-time MVP, six-time All-Pro member, 15-time Pro Bowler and two-time Offensive Player of the Year.
Brady has certainly experienced the highs and lows of the NFL, and on Thursday, he shared a major lesson he has learned — including a cultural "disease" that's prevalent among sports teams.
