Heard about this during the past week - that NE may run quick huddle/no huddle to keep Philly from subbing packages because they like to rotate DL and other personnel to keep fresh. There were stats that showed Philly were gashed frequently on those situations.
If NE's OL keep pressure off Brady it will be a long day for the Eagles. They may then have to blitz some which would surely open the field up for Brady, if the blitz doesn't get to him.
