“Bountygate” was apparently fiction, and Odell Beckham Jr. isn’t a premier playmaker in the NFL.

Gregg Williams’ weekly press conference Friday was contentious, explosive and perhaps delusional.

When asked about Beckham’s comments a day earlier — that the Jets’ new defensive coordinator teaches his players to play “cheap” and “dirty,” and told them to injure the then-Giants receiver in a 2017 preseason game — Williams said he has never coached that way.

“We don’t do that,” he said. “Never done it anywhere I’ve been. We don’t do anything to hurt the team.”

That would seem to be in conflict with his one-year suspension for Bountygate, the scandal in which Saints players were paid for injuring opposing players while Williams was the team’s defensive coordinator. When reminded of that — and the audio of him telling New Orleans players to hurt specific players on another team — Williams grew angry.

“Was that right or wrong? I don’t want to talk about that,” he fumed. “You want to talk about Cleveland?”

“Next!” he barked.

That was only part of the heated nine-minute presser.

He also went off on Beckham, questioning the Browns star’s impact, first mimicking Cowboys owner Jerry Jones by jokingly saying, “Odell who?” When a reporter prefaced a question by referring to Beckham as “one of the most dynamic players in the league,” Williams interrupted.

“That’s your opinion? What’s New York’s opinion?” he said. “The Giants’ opinion? What did the Giants do?”

When pressed about Beckham, Williams declined to address his opinion of Beckham the player, saying, “I already answered that one, next question again.” As for Beckham the person, he didn’t exactly hide his feelings.

“You guys are cooperating, giving him attention,” Williams said. “Just don’t give him attention.”

On Thursday, Beckham started the firestorm. He claimed current Browns players have told him Williams advised them to attempt to hurt him in a preseason game in 2017. Beckham suffered a sprained ankle during that game, and he said he believes it has led to all the leg injuries he has suffered over the subsequent years.

“I had players on this team telling me that’s what he was telling them to do: take me out of the game, and it’s preseason,” Beckham said. “So you just know who he is. That’s the man who’s calling the plays.”

“I had people who were here when he was here telling [them], ‘If you get a chance, take a shot at him. If you can hurt him, I guarantee he’s going to leave the game hurt,’ and stuff like that. It’s something that I’ll never forget.”

Asked by The Post if he wanted to hear Williams’ response, Beckham declined and said: “I’m good.”

Jets coach Adam Gase and defensive lineman Leonard Williams defended Gregg Williams, both saying they have never heard him suggest anyone look to injure another player. Gregg Williams tells the Jets players, according to Leonard Williams, to “play on the edge, live on the edge, but don’t hurt the team.” Jets safety Jamal Adams, friends with Beckham, tweeted, “I luv you, coach! Got your back!” with a picture of the two of them.

“Everything I’ve seen we’re coaching it clean,” Gase said.

Leonard Williams said he believes there is a fine line between being aggressive and going too far, but he insisted his new defensive coordinator doesn’t encourage his players to be dirty.

“He wants us to get the ball, attack the ball, attack every player with the ball,” Leonard Williams said. “It’s just a really aggressive mindset and that’s the type of mindset you should have as a defensive guy. I wouldn’t call it dirty at all.

“When you’re playing that style of aggressiveness, just being nasty on defense, it’s intimidating to an offense. That’s what we try to be. We want to be intimidating. We want to look nasty as a defense. I guess he’s doing his job.”

He will need to be very good at that job this week, facing a motivated Beckham and a Browns offense coming off a disappointing blowout loss to the Titans. The Jets, playing without starting quarterback Sam Darnold (mononucleosis) and possibly star middle linebacker C.J. Mosley (groin), will be in desperate need of a victory after blowing a 16-point, Week 1 lead against the Bills. They could use a big performance from Gregg Williams’ defense.

Expect plenty of fireworks after this week’s war of words.
