So Dave Gettleman finally fell in love with a quarterback.

But what angry Giants fans have every right to ask is this:

Daniel Jones with the sixth bleeping pick?

Cue the John McEnroe tape:

YOU CANNOT BE SERIOUS!!

How do you neglect your depleted defense by passing on a gifted pass rusher like Kentucky’s Josh Allen with the sixth pick of Thursday night’s NFL draft?

Does Jones have enough arm to succeed Eli Manning and carry the team one day and be the Giants’ next franchise quarterback?

Gettleman not falling in love with Sam Darnold, The Other Josh Allen or Josh Rosen a year ago forced him to reach for a projection that satisfies his need to implement the Kansas City model that worked like a charm for the Chiefs with Patrick Mahomes studying under Alex Smith for a year.

And so the firing squad was waiting for Gettleman when he faced the music after Round 1 had mercifully ended for Giants fans.

At the very end of the interrogation, I asked Gettleman what he would tell apoplectic Giants fans to comfort them.

“In time you’ll be very pleased,” he said.

Drafting a quarterback at No. 6 who will not play football this season over an impact defensive player like Allen increases the Giants’ chances of capturing another top-10 pick in the 2020 draft — and not spend it on studs such as Tua Tagovailoa or Justin Herbert or Jake Fromm.

“He’s just perfect for us,” Gettleman said.

Gettleman saw all he needed to see of Daniel Jones at the Senior Bowl.

“I saw a professional quarterback … I was in full-bloom love,” he said.

The 2019 Giants are certainly not equipped to win, and now you have to question whether the 2020 Giants will have a legitimate chance to win with Jones — or 39-year-old Eli Manning if the kid needs more schooling — and with this suspect defense.

“Maybe we’re gonna be the Green Bay model,” Gettleman said, “where [Aaron] Rodgers sat for three years. Who knows?”

He was kidding, right?

Good luck, Saquon Barkley.

Look, no one is saying Jones will be Dave Brown, another Dookie who was not the post-Phil Simms answer. He has smarts and toughness and work ethic and the right makeup and more athleticism than Manning. Gettleman and Pat Shurmur applaud his poise and pocket presence. And there will be some who will take solace in the fact a quarterback guru like Duke coach David Cutcliffe looks at Jones and sees the Manning Bros., all of whom he has coached. And legendary HOF executive Gil Brandt has compared Jones to Peyton Manning at a similar stage. Love Brandt, but he and Cutcliffe are in the minority in that one. Others see Ryan Tannehill.

“We drafted a quarterback that we believe is a franchise quarterback,” Gettleman said.

Sorry, Daniel Jones was not the sixth best player in the draft.

He wasn’t even the best quarterback in this draft. Dwayne Haskins was, and he’s on the Redskins. And Daniel Snyder got him at 15.

Chris Simms, son of Phil? He viewed Jones as a second-rounder.

Sure, it’s nice Gettleman had the kind of conviction on Jones that Ernie Accorsi had in 2004 on Eli Manning, but he could have waited for the draft to come to him and at worst, traded up a few slots for Jones, or at best, take him with the 17th pick.

“I was not willing to risk it,” Gettleman said.

Here’s the thing that worries you about Gettleman: What if he has fallen in love with the wrong quarterback?

There are Giants fans today who only hope they hear Gettleman say: “We didn’t draft him to trade him.”

What if Gettleman and Pat Shurmur were seduced and intoxicated by the dream of finding an Eli clone, in temperament, personality and style?

“I’m going to try to be myself and not be Eli,” Jones said.

The good news: Jones will fit in just fine with the culture.

A text from my high school buddy Giants fan in Los Angeles: “When does the nightmare end?”

Followed by: “Since Gettleman’s plan is to kick ass could you kindly inquire or advise if Jones plays DE or linebacker??? Thank you.”

The 17th pick, the one acquired in the ill-advised Odell Beckham Jr. trade, NT Dexter Lawrence, is a 342-pound hog molly who will be anathema to Ezekiel Elliott, but there still isn’t an elite pass rusher in the house. Gettleman traded Nos. 37, 132 and 142 for cover corner DeAndre Baker at 30.

The Giants are a long, long way from any Super Bowl. But Josh Allen from Kentucky would have gotten them a step closer than Daniel Jones.

Gettleman has told us that you better have mental toughness to play in this market. And now Jones will be measured against Darnold for the rest of his New York career. He better have the same armadillo skin that Gettleman has.

Cutcliffe told me that Jones wanted the New York stage. Jones, about as popular with Giants fans as Kristaps Porzingis was with Knicks fans the night he was drafted, was lucky he wasn’t at the MetLife viewing party. The poor kid would have felt the way Roger Goodell must feel standing in front of the draft audience announcing the picks.

Big Blew it.
