The thought of the Pats* losing to Miami, at home, with the division title on the line is almost inconceivable.
But, I will say this: watch a recent Dolphins game. Even their recent loss to the Giants. They're terrible, yes. But, there's a spark there that really looks like it comes from Fitz. The guy looks like he is playing the best football of his career, just with an absolutely miserable cast of players around him. But, they make plays here and there, and the play calling is pretty solid. You have to respect them, in a way. The Miami FO took to the season with such an obvious tank that the NFL Competition Committee felt the need to get involved. But, the coach, and scrubby players that were left after the FO literally put the entire roster up for sale were not on board. There's effort on the field. The Phins want to win.
But, at the end of the day, their point differential is the worst in the league... by a lot. The only way they could beat the Pats* is if there is a serious disruption in the Pats* defense, like losing Gilmore, and Hightower, and maybe even a third starter to injury, and Brady* having a really, really crappy day. And, even then the Phins would be a long shot.
