It appears to me that Brady has, finally, lost a bit off his fastball. It could be his receivers, but I don't think so.
He's definitely been losing his fastball for the past 2-3 years, but he had his trusted Jules and Danny to find spots/get open, and he's been surgical in the intermediate game. But this year, with no binkies, coverage of Gronk gets tighter and the shutdown corners are looking at Dorsett and Hogan instead of Jules and Danny. Different game and he's been forced into high risk throws. And it shows.
I hope with Edelman returning and maybe Gordon being a threat, things will get easier for the old man
we'll see.
