Let’s look back. They had 5 turnovers in the 2005 AFCDG in Brady/Belichick’s first playoff loss. In 2009 against McDaniels they had the ball starting at midfield late in the fourth quarter with the game tied and… fumbled it away, then lost in overtime on the first possession. The 2013 game was the most acceptable (if you can call an AFCCG loss acceptable) because of the lack of weaponry and then the loss of Talib.
Those are the first three to jump to mind, they lost there in the 2005 regular season as well. But the trend in those last three games is pretty apparent – turnovers and injuries will get you (almost) every time.
