Well long time Pat's fan here...
Regarding Antonio Brown -- Belichick has had an infatuation with this guy for a long time (probably because he's faced him so often and game planned against him). They offered a first round pick for him to the Steelers before the Steelers traded him to the Raiders. I don't like the guy, I have my doubts, but if anyone can right that ship, it's Belichick and Brady.
Pat's passing offense probably isn't their strength this year, it's their defense and running game. But a lineup of Edelman, Brown, Josh Gordon and James White, and D. Thomas?? And a possible Gronk return? That could be deadly. But it's football, anything can and will happen. The Pat's could lose brady week one and this whole season could turn into a disaster. Look at the Cinderella Browns in week one...they get killed ny Tennessee. Tennessee has issues all over that team...offensive line, quarterback...yet they wiped the field with Cleveland and Baker Mayfield. You just don't know.
