I am now fearful about the Packers game. When Belichick's team has been upset it's usually by a young QB, who no one knows much about, and little film to study his tendencies.
When Belichick doesn't have enough film on a guy he can't use his masterful Coaching and his great game planning to give the Pats their usual out-sized advantage. With all the Pats injuries on the defensive line, the Pack might be able to run enough, to allow Flynn to pass a lot less and conservatively.
How many games have the Pats lost to young QBs? You only have to look at their last loss, when the Browns and Colt McCoy did them in.
Flynn is not a raw rookie like McCoy. He is more like Matt Cassel, four years into his career, and his coaches saying he is a QB on the make.
