ESPN Stats & Information broke down the data and found that, compared to the Patriots' three victories, Brady's completion percentage drops more than 34 percent and his passer rating plummets almost 63 points in the second halves of their two defeats.
Brady was 5 of 14 for 63 yards in the second half of Sunday's overtime loss to the Denver Broncos. He didn't throw an interception, but he lost a fumble that killed what could have been the game winning drive inside the final two minutes of regulation time.
Brady has completed 72.6 percent of his passes for 183.3 yards, has averaged 7.5 yards-per-attempt and has four touchdowns with no interceptions in the second halves when they've won.
When the Patriots have lost, he has completed 38.2 percent of his passes for 64.5 yards, has averaged 3.8 yards per attempt and has zero touchdowns or interceptions.
