Tom Brady said he's not greatest quarterback of all time and lent credence to an interesting theory about his career

After Tom Brady led the New England Patriots to a wild comeback from a 28-3 deficit in the Super Bowl, many thought he had cemented his status as the GOAT, the greatest quarterback of all time. At 39, Brady has won five Super Bowls and shows no signs of slowing down — in fact, he improved upon two of his biggest weaknesses this past season. In an interview with ESPN's Ian O'Connor, Brady deflected that title and argued what many people have said about his career: that he's a product of the Patriots' rock-solid system.
