Even if they didn't get turnovers in these last 3 games, they would've likely went 3 and out. They're getting turnovers because Brady is eager to make something happen and nothing is happening until the 4th quarter it seems.
Ever since Brady&Belichick tied the record with Marino&Shula, the offense has been stinking up the joint. Maybe if they could finally get this 117th win, everything will be fine again. Right now, the offense is being way too conservative and defenses are taking advantage. I think it has more to do with the offense's lack of execution than it does defenses getting to Brady, but whatever... something's gotta change.
