#The biggest Giants concerns to emerge from nightmarish day

No matter who you are, no matter where you have coached, you will take that first NFL win with you for the rest of your life. And the sooner you get it, the better.

And it doesn’t matter whether you get it against the Joe Montana 49ers, or the decimated Nick Mullens 49ers.

Because until you get it, you begin to wonder when and whether you will ever get it.

Joe Judge is 0-3 after Sunday’s disgrace of a 36-9 loss to the 49ers’ B team and he has every reason to wonder when and whether he and his 2020 New York Football Giants will get it.

On a day when the whole damn team regressed, when one coaching staff provided a clinic to the other, when the difference between a championship-style program and one still mired in a never-ending cesspool of muck was glaring, your only chance is for your young quarterback to raise the level of his play without Saquon Barkley by his side.

Daniel Jones did not, and could not overcome the calamity and chaos and incompetence that swirled around him.

Giant step back for the rookie head coach’s program.

Giant step back for the quarterback.

If Judge is not better than this, if Jones is not better than this, this will be another 4-12 nightmare.

Questions rearing their ugly head about whether general manager Dave Gettleman has handed the rookie head coach enough of the right players.

And if Jones cannot put an end to the turnover train — six now following an errant albeit catchable pitch that Evan Engram fumbled and a costly interception and 10 career games with multiple giveaways — fears, as premature as they are right now, are sure to grow that perhaps he won’t be The Next Eli Manning.

The concern, if you are a not-as-long-suffering-as-a-Jets-fan-but-long-suffering-enough Giants fan, is that Jones’ growth will be stunted by an environment that remains hardly conducive to his development.

“I think it was definitely disappointing,” Jones said. “I don’t think any of us came in expecting this.”

Jones was better with his legs (49 yards rushing) than he was with his arm, better with his legs than newcomer Devonta Freeman and the other backs who can’t run but they can’t hide either behind an offensive line that no one can argue is fixed.

But Jones (17-for-32, 179 yards) was badly outplayed by Mullens (25-for-36, 343 yards and 1 TD), which was alarming on two fronts: Mullens didn’t have his three best weapons, TE George Kittle, RB Raheem Mostert and WR Deebo Samuel.

And the 49ers played most of the game without their three top cornerbacks. And yet: no red-zone snaps at all for Jones and an absence of deep shots.

“We understand we can’t let that affect our confidence going forward … not let this situation define us and understand what we need to do to move forward and improve as a team,” Jones said.

Judge became so desperate that he called a fourth-and-1 quarterback sneak from his 30 late in the third quarter down 23-9.

“I wasn’t surprised by the call,” Jones said. “I think in that situation, I appreciate Coach’s confidence in us and giving us the opportunity to convert that. I gotta do a better job finding the opening there, and getting a yard.”

Coach: “I’m not gonna apologize for being aggressive in that situation.”

You have to like that Jones points the finger of blame at himself, and only himself.

Asked about the pitch, slightly behind Engram, he said: “Just a poor pitch. Something we worked on all week. I gotta do a better job there.”

Asked about throwing the ball to linebacker Fred Warner in a first half when he possessed the ball for only 7:34, he said: “Poor decision in that situation. You can’t afford to turn the ball over and force the ball across the middle to Evan there … certainly a costly mistake.”

Big Blue broke in the second half. That’s what happens when you’re on the field for nearly 40 minutes. The Fighting Joe Judges were knocked on their keesters.

“People that work blue-collar livings like my family did growing up, you just wake up every day no matter the circumstances and you go back to the grindstone,” Judge said. “That’s what our team’s gonna do. We’re not looking for excuses, we’re not pointing fingers, we’re not looking for shortcuts, we’re working on building this thing and building this thing the right way for this area. … In terms of the people in the area want to know the direction this program’s going, I can assure you that I take a great deal of pride and I put a lot personally into this to make sure that the product they see on the field they can be proud of. I can assure you we’re working the same way they work every day to get our butts back to work, to get it right, and get it going forward.”

Blue Monday, not Blue Collar Monday. Following a Sunday where it all went backward.
