Blowing out Cleveland and Tennessee isn't a concern. Both teams beat themselves every week. There's some talent on the Dolphins, especially the defensive line, but the mismatch is on the sidelines.
The Dan Campbell thing is the most interesting part of this game. He's inexperienced and he's surrounded by guys who don't have a depth of pro coaching experience. It's not like Norv Turner is sitting up in the booth or anything.

Campbell's coaching resume is basically serving as a Tight Ends coach with the Dolphins under Tony Sparano and Joe Philbin. Not exactly out of Bill Belichick's league. I can't imagine Campbell will be making many in-game adjustments that Belichick can't handle when things start getting squirrelly.
The OC is a guy named Bill Lazor who has been around for ten years or so but there's no reason to think he can outcoach Matt Patricia. The DC is a guy named Lou Anarumo with even less experience - basically a DBs coach who is in his first stint as a DC. Josh should own this guy. Anarumo is in his first stint looking at the full range of what an offense does and scheming to attack weaknesses or take away strengths.
The Dolphins basically sucked at rushing the passer under Philbin, but did have success the last two weeks against a rookie and Brian Hoyer. Tom Brady is an entirely different level of quarterback for Anarumo to match wits with. Josh and Belichick will sniff out what they're trying to do and attack it.
Short week for these guys, too. On the road.
I smell a blowout.
