Eli Manning can throw four interceptions and no one wearing Giants blue will think the world is ending.

The Giants’ offensive line can give us a stinker and everyone wearing blue who yearns for the good old days of Chris Snee and Shaun O’Hara and Rich Seubert and David Diehl and Kareem McKenzie will think the world is ending.

Here’s the word from the Giants offensive line:

It isn’t.

It won’t.

Come Sept. 11 against the Cowboys, here is what left guard Justin Pugh expects the personality of Manning’s bodyguards to be:

“That teams know when they come to play us, that they’re in for a long day. It’s not gonna be, ‘Oh, we’re going against the Giants’ offensive line, we can set the tone.’ I want us to go out there, set the tone and be the more aggressive, more physical team, and when people come in they’re like, ‘We’re gonna have to work to get everything we’re gonna get because they’re not gonna hand us anything.’ ”

It only seems like an eternity since a Giants’ offensive line has set the tone.

“The consistency to do that is the biggest obstacle that we face,” Pugh said. “You can’t win with an offensive line that’s up real high and then real low. I’d rather take a guy that’s gonna give 80 percent every week, you know where he’s at instead of a guy that’s 90 [percent], then 50 [percent], then all over the place. I think that’s where we’re gonna win games this year, and that’s across the board in every aspect, every facet of the game, every position has to do that.”

Pugh didn’t play in Buffalo, where all the red flags and storm warnings went up around an offensive line that hasn’t built up enough equity for coach Ben McAdoo or for anyone else to dismiss an alarming lack of physicality.

Here’s the word from the Giants offensive line:

We are not Marshmallow Men.

“You never want someone to come up and say, ‘There wasn’t toughness,’ or I hate to see that word ‘soft’ thrown around anywhere when it comes to a football player,” Pugh said. “That’s something you don’t need talent to be a tough guy out there. So I think everyone in that room can get that job done, and we’re gonna get it done.”

From left to right, LT Ereck Flowers, LG Pugh and C Weston Richburg are expecting to make the leap in their second consecutive year at their respective positions.

Here’s Pugh on Flowers:

“He has all the tools to be a great left tackle in the NFL, and you look at it, he’s got the size, he’s got the athleticism, and that’s on him. He’s gonna continue to improve and get better, but as quickly as he gets to that point where he’s a perennial Pro Bowl guy, I can’t make that assessment right now. I think he can every year be a Pro Bowl left tackle.”

Here’s Pugh on Richburg:

“I already think Weston’s one of the best centers in the NFL.”

Here’s Pugh on Pugh?

“I think he’s a pretty damn good player, too (smile). Obviously, I got things I gotta get better at. But I’m gonna go out there and fight. I’m a competitor, and I think that’s something that I bring to the table. You can turn on the film, I’m not the best technique guy out there, but I’m gonna go out there and compete. I don’t like to get beat by anybody, so I’m gonna go out there, I’m gonna leave it all on the field, and that’s something I pride myself in.”

Pugh carried his passionate defense of his linemates over to the right side.

“There’s a clip in the Buffalo game where [right guard] John Jerry literally throws a guy 5 yards away,” Pugh said. “So If you look at one of the first drives, you’ll see John Jerry literally throwing another grown man 5 yards in the air. Everyone always wants to try to come at the right side of the offensive line. John Jerry, I think, is one of the better underrated guards. Any right guard you want to give me in the NFL, I don’t see where they’re that much better or better at all than John Jerry. And Marshall Newhouse, we always are pointing out the things he’s doing, ’cause he’s always doing the right thing. There’s a lot of things that people don’t know, why things collapse or don’t go right on a play, so to put it all on two guys or say that something’s going on with them is definitely unfair.”

Richburg, asked what he would say to Giants fans all but pulling their hair out, said: “Second week of the preseason.”

The Giants are counting on the continuity of all five returning starters helping chemistry, camaraderie and cohesiveness.

“We know how to reach each other and how to speak to each other when the bullets are flying like that,” Richburg said.

The Giants didn’t try to move up to draft tackle Jack Conklin. Eugene Monroe retired. Right tackle Anthony Davis is back with the 49ers.

“You never want to get too high, you never want to get too low,” Pugh said. “If things don’t go the way you want it to, you flush it out of your system and you get back and get to work, I think we had a good day today out here.”

They will need one Saturday night against the Jets. But especially against the Cowboys.

“We want to finish each play, and from there finish a game,” Richburg said. “That consists of being physical, having a mean attitude and really getting after people.”

If the burden of proof is on anyone, it’s on them.
