Brady definitely was a huge factor in the system's success offensively. Was he all the success? No. New England went 7-9 while finishing 4th in rushing yards (definitely aided by Cam of course) with one of the worst passing offenses in NFL history. Michel & Harris missed games and still averaged 5.7 and 5.0 YPC respectively. They didn't just stumble into that ass over teakettle.If you look at what the Pats drafted the last ten years? Almost definitely Brady. Their draft record is abominable and now that shit is coming home to roost.
