What stands out about Tua Tagovailoa’s impending exit is how it’s the easiest decision of this new Miami Dolphins regime’s ragged inheritance.

Solving the salary-cap chaos, weeding out the front office, rebuilding the rickety roster, deciding on fair contracts to players while dropping the pay-everyone lavishness of recent years — that’s all a fragrant bedpan new general manager Jon-Eric Sullivan inherited.

But Ta-ta-to-Tua?

It’s not a football or, by now, a financial decision. Owner Steve Ross signed off on getting no return on the $99 million owed Tua in hiring this new regime. So, it’s a diplomatic decision at this point. It’s:  How does The New Guy show how he works in his opening steps?

It’s clear Tua will be dumped — oops, there’s no need for a pejorative verb like that. Tua wasn’t a bad guy with the Dolphins. Odd, at times. But aren’t we all?

Sullivan had the right tone in answering a question about Tua and the quarterback issue in a function for select ticket holders Thursday night.

“Of course, we’ll be looking at other quarterbacks in this draft and every draft hereafter,’’ he said. “But, look, Tua was in my office the other day, if I’m being perfectly frank. We had a great conversation.

“Tua has been a very good player in this league. He’s done a lot of really good things for the Miami Dolphins. You guys should be proud to have him and having had him.”

He concluded: “We’re getting close to a decision. When we do we’ll let Tua know whether he’s going to be part of this or not. And we’ll move forward. But rest assured that we will add competition to that room one way or the other to make it the best that we can.”

That’s the way it’s done. The only way Sullivan can be any nicer for his next meeting with Tua is by channeling the George Clooney character in “Up In The Air,” who fired people by saying, “Anyone who has ever built an empire or changed the world sat where you are now.” (A Sam Darnold, Jets-to-Super Bowl reference would work, too).

Again, they’re moving on from Tua. As they should. As they must. As anyone who saw him play last season or, let’s be honest, how the Dolphins had to navigate the last few seasons, must agree.

This is best for Tua, too, as he knows (Cue his, “It’d be dope,” quote in December). The more intriguing question is if he wants to play on in the NFL or just wants his money. He won’t retire and walk away from $99 million — would you?

But does he love football enough to try to claw his way up from a backup role over the next few years, even with his obvious health issues? Again, would you?

Back to the Dolphins. Their biggest contract will remain their biggest headache for a third year running — you know, since they showed Tua the money. That’s done. There’s no need to run more tire tracks over the old regime for not knowing what they were doing. (I’d need new tires, too).

Could the Dolphins trade Tua? Maybe by eating tens of millions and offering draft picks. Bottom-line: There’s no market for a six-year veteran with a big contract and health issues who was benched for a seventh-round rookie.

Could the Dolphins keep Tua to get something for his money?  A new regime deserves a fresh start. That means the quarterbacks, too. Whoever the starter is doesn’t need to have a few bad games and hear people whisper about Tua. Anyone who’s seen Tua play of late really doesn’t want to whisper that, either.

The best part of a new regime is everyone turns the page to Page One. Old problems get rebranded as new opportunities. Surely, you’ve done this dance step enough times over the past two decades with the Dolphins to have muscle memory how it works.

Sullivan inherits the worst mess of any of the rebuilds. The bloated salary cap. The defense without a proven cornerback or pass rusher. The offense without a quarterback and needing help at receiver, tight end, guard and maybe a tackle.

In that context, Ta-Ta-To-Tua isn’t some complicated decision. It’s diplomacy. Be nice. Wish him well. And hope the new regime fixes this franchise.
