Is anyone concerned

I doubt Brady lasts a season once he starts playing in a division that's way more competitive, and home field advantage isn't as good as it was in NE. He couldn't even catch Brees last season after the injury. Brees threw still 3 more TDs than Brady did. He's on the decline way more than Brees is. Some of Brees records will fall one day.

This exactly!! We'll find out how good Brady still is in a division that won't represent half a dozen or so glorified scrimmages.

No doubt that Brady is one of the all time greats but his records and stats were greatly enhanced by the fact that he played in a pretty soft division most of his career...……...no matter that the east coast writers are quick to defend him by saying that the AFC East was a very competitive division.
