The way his Jets defenders talk about him, you wonder whether Gregg Williams might have gotten Mahatma Gandhi to run through a wall for him.

Williams is The Mouth That Roars in the Atlantic Health Jets Training Center, and his sound and fury this week were aimed primarily at precocious Raiders rookie running back Josh Jacobs. Jon Gruden thinks the Raiders can run the football against anyone, and Williams thinks no one can run the football against his Jets at a time when he is fielding the No. 1 run defense in the NFL.

Gruden versus Williams isn’t quite Bill Belichick versus Bill Walsh, but it is one compelling game within the game.

“You better be ready to wrap up,” Williams instructed his troops. “If you go in there with that soft stuff, Jacobs is gonna run you over. He’s not an easy guy to take down.

“If you don’t want to play the run, go ahead and stay inside.”

Williams was the Browns’ defensive coordinator 14 months ago when Gruden got the better of him in a 45-42 overtime victory. It was Gruden’s first win since returning to the sideline and it was engineered by Derek Carr’s 437 yards and four touchdowns.

“I think it’s Year 2 with Jon,” Williams said. “I see a lot of the same things that I’ve seen out of quarterbacks he’s coached for a lot of years. I see Derek doing the same type of accurate throws he’s always done. But he’s not afraid of taking a check-down for the first time in his life. Jon over-coaches that.”

Carr won’t have Amari Cooper this time, and he won’t be in the Black Hole.

“You just don’t know where you can get hit from,” Brandon Copeland said. “You never know if you’re gonna get pressure from your inside linebackers or pressure from Jamal Adams or pressure from just a four-man rush or people dropping out in coverage. I think that when you can do that, it’s hard to scheme. It’s hard to predict what we will be in on critical plays in the game.”

Jacobs — 923 rushing yards and seven touchdowns, with 17 receptions for 144 yards — is now The Straw That Stirs Gruden’s Drink.

“He’s a very sudden, powerful, one-cut kind of a runner,” Williams said. “We need to make sure we understand that you don’t want to be in space by yourself with him because he can make you miss.”

They couldn’t miss Williams’ voice this week.

“You can tell that when he gets fired up, it’s premeditated,” Tarell Basham told The Post. “He heats himself up. He turns his own stove on and watches it explode. But then he’ll reel everybody in and get everybody on the same page. He just wants you to know how serious he is about certain things and how important certain things are to this defense and how we play in order for us to be successful.”

It only seems as if Williams shows up with laryngitis on game day.

“You know how much he cares and how passionate he is about doing things correctly,” Copeland said. “Your ear’s on fire so to speak. But you also understand that it’s coming from a place of love, his form of love, and also his standard of perfection.”

His standard of perfection revolves around population to the football. And anyone can be part of the population.

“He doesn’t let things go idly by,” Jordan Jenkins said. “You could have been first-round draft pick, second-round draft pick, if you’re not doing your job you’re not gonna play. Gregg keeps it 100 with guys. He plays guys that want to play. He wants guys that aren’t selfish. He wants guys that give a damn about your brother that’s going to war with you, a guy that will do his job even though he might not make a play or something like that. He just understands how to get the most out of guys.”

Williams doesn’t look for supermen. He looks for super teammates.

“One thing that he’s always told us is don’t worry about being the best in the world,” Basham said. “Worry about being the best that you can be.”

Williams has told his players in no uncertain terms that they are a ways from being the best they can be.

“It’s something that we need to eliminate in our defense and we don’t want the other team to know what it is that we’re trying to eliminate,” Copeland said. “We let certain things happen over the past couple of weeks that are on film and that we need to get off of film.”

Defending the screen perhaps?

“We didn’t leverage it correctly on how we go about leveraging things,” he said. “I think we can run a little bit faster and I think that’s one of the messages that got through here this week is that their effort better be a heck of a lot better, otherwise they’re going to work for you guys [media] next week.”

Williams once had a Chucky blitz in his arsenal.

“They have a very aggressive scheme,” Gruden said this week. “They’re not afraid to load the box with the Bears’ defense, that’s Gregg Williams’ style. They cheat their corners in run support, they’ll tackle ya.”

And then there’s sack-happy Jamal Adams.

“He’s a fearless player,” Gruden said. “He’s one of the most aggressive players that you will see. His playing speed is rare. He’s a linebacker playing defensive back. He’s a defensive lineman playing defensive back. And he’s a defensive back deluxe. He can do it all.”

Williams versus Gruden.

“When people tell you that they’re putting a front out there that you can’t run against, our guys are blind to that,” Raiders offensive coordinator Greg Olson said.

Williams plans on opening their eyes.
