The most important hire, of course, is the head coach, and the Giants got that done in high-flying fashion with the wooing and securing of John Harbaugh to a five-year deal to bring the franchise back to winning ways.

The second-most important hire comes next. Who Harbaugh brings in as his offensive coordinator will be crucial to the further development of Jaxson Dart.

Harbaugh’s rise through the ranks came mostly as a special teams coordinator and he also spent time as a defensive backs coach. He relies on his coordinators to run the offense and defense.

It certainly could come as no surprise if Harbaugh looks to replicate some of what he had with the Ravens and look to turn the Giants’ offense over to Todd Monken.

He is the favorite to land the job, The Post has learned.

“He does a great job,’’ an NFL coaching source told The Post.

There are steps to take, as the Giants must interview two minority or female candidates from outside the organization before they can make a coordinator hire, in accordance with the Rooney Rule.

With so many head coach vacancies — now eight, with the Giants closing their opening — and staff upheaval around the league, there are 12 teams currently without an offensive coordinator.

Competition for these jobs will be hot and heavy.

Harbaugh likely will not have to do any arm-twisting to reunite with Monken.

Monken, 59, has worked with a wide variety of quarterbacks.

He was with Harbaugh in Baltimore the past three years, dealing with the physical brilliance and at times medical issues with Lamar Jackson.

That relationship reportedly ran its course and Monken last week admitted to not getting the best out of the two-time MVP quarterback.

“I didn’t coach Lamar well enough,’’ Monken said on the “Ryan Ripken Show” last Thursday. “I didn’t have as good a relationship as I could have. I didn’t do the things we needed to do this year to win enough games to give ourselves a chance.’’

Monken was with the Browns as offensive coordinator in 2019 when Baker Mayfield in his second NFL season passed for what remains a career-high 3,827 yards.

He was the offensive coordinator and quarterbacks coach at Georgia in 2021 and ’22 for Kirby Smart, helping unheralded Stetson Bennett and the Bulldogs win back-to-back national championships.

“You’ve got to have a great quarterback,’’ Monken said. “Lamar Jackson is a great quarterback. That gives you a chance every year. I want to be where they have a great quarterback.’’

There is little doubt most offensive coordinators will want to work with Dart. Brian Daboll was in on the nascent stages of Dart’s NFL development and did a fine job with him. Monken would be an experienced, respected voice for Dart to hear in his second NFL season.

Monken interviewed Wednesday for the Buccaneers’ offensive coordinator job.

It certainly seems logical that Monken will want to join Harbaugh with the Giants.

Together, Harbaugh and Monken went 13-4 and 12-5 before this season’s dip to 8-9, with Jackson missing four games.

Despite missing out on the playoffs in 2025, Monken remains a believer in Harbaugh.

“Are you going to tell me John Harbaugh’s message after 18 years as a head coach, the best I’ve been around, besides Kirby Smart, those two guys, that all of a sudden the message isn’t clear?’’ Monken said. “He’s the best to me of motivating and directing and keeping a team moving in a certain direction. And I’m not saying that — he may never hire me again, he might think I’m just come clown that should be working at IHOP — I’m just saying I think it’s an easy cop-out instead of saying ‘You know what, I’ve got to coach better, I’ve got to freaking play better, that’s what I’m paid to do. That’s a fact.’’

Monken is not likely to be headed to IHOP any time soon, unless he wants some pancakes.
