Yeah, he beat Belichick by 1 pt in Mac Jones first career game and then again in a meaningless game (for the Pats) in week 18 as the Bills were facing the Jets @ home with the tiebreak. Another one of his Pats wins was when the Pats were resting guys in the playoffs for week 17.
Flores has had a couple nice streaks of games against a bunch of poor teams, 9/10 wins last year were against .500 or below teams. This year, his 7 game win streak came against bottom-feeders and non-playoff teams (Jets x2, Giants, Texans, Panthers, Ravens, Saints). It would be much more impressive if he didn't have two 7 game streaks going the other way.
He was also outscored by 137 points in his first 4 games coaching, you or anyone on this forum could go out there blindfolded and coach the Dolphins 4 4 and it wouldn't get that bad.
People have trashed Tua but he's still very young and has only played in like 20 something games. 13-8 as a starter. I still think he could turn out to be a great QB, if it's true about the rifts between Flores and Tua then I def don't want Flores cause I'm sure there will be plenty of growing pains for Fields like Tua in the coming seasons and the last thing we need is another fractured locker-room.
