Gotta love Stafford being open to being traded anywhere but New England because we rehired that loser Patricia. Embarrassing
From what I read, it's not clear exactly why he didn't want to come to New England.
I would guess it's far more likely that he didn't want to go to a place where his top receiving options would be Jakobi Meyers and Rex Burkhead.
One article I read pointed out that Stafford has spent his whole career playing in a dome, so the idea of playing outside in New England may have been unappealing to him, also.
What it definitely says is that the Patriots can't rely on being a place where players necessarily want to go, because they no longer represent an easy ticket to the AFC Championship game and beyond. The Patriots are a team with a reputation for expecting a lot from players in terms of discipline and sacrifice, on top of being located in a small market with cold weather. It's probably a tough sell at this point.
