Brian Flores and Patrick Graham get the first crack. They are the Miami Dolphins’ defensive brain trust. They’re having enough issues trying to keep players on the reservation as the Dolphins deal with a major rebuilding project after stripping away most of their assets.

But now they have to deal with an already stacked Patriots offense that just added Antonio Brown. The former Patriots defensive play caller and defensive line coach have to devise a plan to stop a collection of talent that might prove to be unstoppable once Josh McDaniels sorts out all the moving parts.

Assuming Brown buys in with the long-held team-first mentality that’s been a cornerstone of six championships in New England, and assuming he runs the assigned route and doesn’t freelance, the Patriots are going to make quite a few opposing defensive coordinators miserable.

Steelers DC Keith Butler didn’t come close to shutting down Tom Brady & Co. during Sunday night’s blowout, and that was without Brown in tow.

It seemed like the Steelers thought stuffing running back Sony Michel was the ticket to stopping the Patriots. If only it was that simple.

Brady and McDaniels just went to Plan B with a temporarily stalled running game. Using a variety of formations, Brady went to the air and picked the secondary apart with wideouts Josh Gordon, Julian Edelman and Phillip Dorsett. And let’s not forget his favorite third-down back, James White. Save for stalling in the red zone (0-for-3), it all clicked.

The thought of adding Brown into the mix is insane. And, if you’re a defensive coordinator trying to devise a plan to defend against the Patriots collection of wideouts and backs, it’s almost unfair.

SiriusXM NFL analyst Solomon Wilcots, a former defensive back in the league, wouldn’t want to have the job of attempting to keep Brady & Co. off the scoreboard.

“I’d say, pick your poison,” Wilcots said Monday when asked about the new Patriots arsenal. “Not many people can cover Antonio one-on-one. I’ve only seen one or two guys have any success, and at best, that’s 50 percent. I’ve seen (Cincinnati’s) William Jackson III have a good game against him. I’ve seen (Jacksonville’s) Jalen Ramsey have a good game against him. The other guy was Stephon Gilmore. But now he’s playing with him. So now you have to double-cover him, and that moves the ball elsewhere. Josh Gordon is going to be a handful. As the season goes on, he’s only going to get better.”

Even though he’s 31, Brown is coming off a season where he amassed 104 catches, 1,297 yards and 15 touchdowns. He had four catches of 50-plus yards. Can defensive coordinators afford to single cover him? That’s highly unlikely. So doubling him, wherever he lines up, will free up either Gordon or Edelman, or both. If defensive coordinators flood the middle of the field, fine, Brady will shoot it down the sidelines to either Brown or Gordon. The attention on that trio will also free up James White or Rex Burkhead or both. Many defensive coordinators have targeted White and done their best to eliminate him on third down. Well, that’s going to be a tall order this season.

So defensive coordinators will have to decide who gets doubled and who’s left for White and Burkhead.

“With Bill, it’s all about matchups. Because they have the ability to be whatever they need to be to win games,” said Wilcots. “You add in Antonio, they can almost ensure whatever matchup advantage they want. They have a way of doing that.”

Good luck to Flores and Graham, Jets defensive coordinator Gregg Williams, the Bills’ Leslie Frazier right on down the line. The Dolphins might catch a bit of a break with Brown still getting acclimated to the offense (assuming he plays). But they still have to prepare for him. During a conference call Tuesday, McDaniels didn’t necessarily see a need to force-feed Brown right off the bat.

“We have a lot of good football players on our team and a lot of guys that have roles that they can perform well. We’ve got to go out there and put our guys in good positions to be successful, hopefully, with a really good week of practice,” he said. “We’ll see how it goes as we go forward, but certainly we’ve always had the same concept in terms of our run game, pass game, our offense in general. We’re going to try to throw it where we’re supposed to throw it and we don’t try to force the ball anywhere or to anybody because that’s not necessarily the way we do it.”
