A primary job of a columnist is to offer unsolicited advice to anybody, and here’s some for Miami Dolphins owner Steve Ross: Move on from Tua Tagovailoa.

It’s time. It’s obvious, too.

Maybe not move on from the final three insignificant games of this season after Monday’s 28-15 lackluster loss in Pittsburgh. Maybe they decide he’s useful as a small bridge – a pontoon? – to the next guy next year considering he’s a $99 million anchor right now.

But if keeping him is all about owing money, here’s 20 bucks. Please, take it. You could even announce a Tua Tariff on every season-ticket holder and that’d be a starter’s kit toward paying him off.

Here’s the bottom-line: This era’s over. Done. Tua plays older than Aaron Rodgers and Philip Rivers combined at this point. Coach Mike McDaniel knows it by the game plan he keeps using, this one dependent on the run where they don’t throw downfield. He can’t rely on the quarterback play and strategize to hide Tua in plain view.

The Dolphins were down 21-3 in the third quarter, then 28-3 early in the fourth, and had no giddy-up to their tempo. “Flabbergasting,” ESPN’s Troy Aikman called their waving the white flag by moving so slow. The two-minute offense isn’t limited to the final two minutes, is it?

It’s like they were the team with the lead or wanted to run out the clock. And why not? Tua had 60 yards passing through three, empty quarters. His limitations were limiting the offense again.

Forget the big numbers from there. The two touchdowns. The 113.2 game rating. Those irrelevant numbers meant nothing, considering they came after the Dolphins were so far out of it Pittsburgh was trading easy yards for time off the clock.

What mattered is this offense had minus-20 yard in the third quarter on two, three-and-out possessions thanks to Tua being sacked twice. Rodgers, meanwhile, directed Pittsburgh to 71-, 72- and 71-yard touchdown drives. That was the game. The era, too.

The problem isn’t Monday’s loss. It really isn’t, even though it ended any fantasy of making the playoffs. It’s hard to win five straight games in the NFL. But the manner the Dolphins won and now lost is the issue. All the issue to this team that were obvious in this recent winning stretch — they’re not getting anything from the quarterback — crushed them this night.

The Dolphins have one script to winning: Good defense, good running game and ask the quarterback not to throw interceptions.

Riding that plan in this recent stretch had the Dolphins thinking they were close to beating a decent team in the cold. That was on the checklist entering this season. McDaniel even took them to Pittsburgh a day early to acclimate to snow and cold. Update: They’re winless in their last 14 games under 40 degrees.

But this night wasn’t about weather. You could play in the cold, the rain, the sun — anywhere — and you aren’t winning with quarterback play like this. It continued a mystifyingly bad season for Tua. Is his body deteriorating from all its issues? Are his ankles, as he’s mentioned, a problem and his hip affecting his throwing?

He lobbed a bad interception in the second quarter — his league-leading 15th. He then (again) slid early on a 3rd-and-2 that meant the Dolphins had to punt the ball back to Pittsburgh. His offense had a field goal through three quarters against a Steelers defense that entered Monday as the 28th ranked and was without its best player in T.J. Watt.

Forget the fourth quarter. Don’t overvalue this recent stretch, too. It’s been a nice stretch. It said something about the team caring and McDaniel’s leadership. But baseball has a saying, “Don’t trust losing teams in September.” Do you trust a team that stood 1-6 team for a good month?

The No. 1 issue for the Dolphins this offseason is what it’s been for most of the past quarter-century. They need a quarterback. They can pretend they don’t. They can also keep finishing behind Buffalo and now New England for the next decade.

Tua’s contract is a problem this organization, starting with McDaniel, brought on itself. But look what Denver did with Russell Wilson. It’s a parallel problem. Denver released Wilson two years ago when Sean Payton came aboard and took a $52 million hit in dead-cap money. It had another $32 million hit this season. It also is 12-2 and found a quarterback in Bo Nix.

If the Dolphins release Tua as a designated post-June 1 cut, he’s a $66 million dead-money hit next year and $33 million the following season. Not good. But draft a good quarterback and his rookie contract will cover for that.

So, Denver offers a road map for the Dolphins if they know what they’re doing and can find the right replacement. Do they draft a quarterback? Do they polish one off the scrap heap like a Baker Mayfield, Sam Darnold or Daniel Jones?

That’s getting ahead of the issue confronting Ross. The issue right now is who makes the decision. It takes talent to find talent. The Dolphins haven’t had talent in the front office over this last, lost decade when they passed on the likes of Lamar Jackson, Josh Allen and Justin Herbert.

Does Ross status-quo everything with McDaniel and interim GM Champ Kelly? Does he go out and find the best personnel name available, considering that probably means moving on from McDaniel? Or is Kelly the best available?

We’re at the point again where Ross has to do what’s best for the organization and not any single quarterback or coach or front-office name. He’s made nice with people inside the Dolphins since he bought the team in 2009. It’s gotten everyone nowhere.

Monday showed that again. It wasn’t the cold. It wasn’t the road. It wasn’t even Pittsburgh, a good-not-great team. Pittsburgh did have a 42-year-old Aaron Rodgers look like he was 35 again. Tua looked old. Tired. In constant trouble.

There will be talk of playing Zach Wilson or rookie Quin Ewers. Whatever. The larger question is what’s coming.

Tua’s era is done.

The next issue is what the Dolphins do about it.
