Meet Odell Beckham Jr.’s latest enabler: Cris Carter.

The Hall of Fame receiver, who’s serving as a personal trainer and mentor to Beckham, joins a growing list of enablers to the Giants’ temperamental and sometimes undependable star receiver that already includes the Giants front office, coaching staff and fellow players.

Beckham, whom Giants general manager Jerry Reese after last season implored to become more mature as a “face of the franchise,” has drawn headlines this week for skipping the team’s OTAs.

Obviously still oblivious to poor optics (see last season’s social media photos with Justin Bieber on that boat in Miami days before the Giants’ first playoff game in five years, a loss in which he dropped a touchdown pass), Beckham this week has been pictured with Johnny Manziel, a poster child for immaturity and poor career decisions.

Beckham catching passes from Manziel this week instead of his own two-time Super Bowl MVP quarterback Eli Manning at a time when the rest of the team is together for voluntary workouts? Not a good look.

Here comes Carter, the former Vikings and Eagles great receiver, who in an interview on Colin Cowherd’s “The Herd’’ on FOX Sports Radio on Friday not only condoned Beckham blowing off the Giants OTAs, but he napalmed the team’s coaching and training staff.

Carter, who worked with Beckham this week in Los Angeles, made the point he never went to minicamps or OTAs as a player and that Beckham doesn’t need to, either.

“Odell has the ability to tap into people like myself and [former 49ers great receiver] Jerry Rice and other people if he’s not at [the team] facility,” Carter said. “We can’t go into the Giants facility and help him. The Giants receivers coach [Adam Henry, who was Beckham’s position coach at LSU from 2012-14], he probably thinks he knows more football than me. Odell’s opinion of that is a little bit different. I teach a little differently than the coaches, so he’s getting some different information from me.

“I didn’t go to minicamps and OTAs. We missed them. We would get an agreement with the coach — ‘Coach, when do you need me to be there?’ Randy Moss and those guys came to Florida to train with me.”

Carter, referring to Beckham’s absence from the OTAs, said: “This is not something that’s new. It’s because of the boat trip. It’s because of who he is. It’s because of the loss in the playoffs [to the Packers in the wild-card round], and because the general manager went out and said Odell has to be mature.

“[Reese] didn’t know Odell wasn’t coming to the OTAs, and now he’s got to answer questions on comments he made months ago.”

Carter’s premise that he can offer Beckham different “position-specific” information than the Giants coaching staff has some merit, considering Carter’s accomplishments in the game. So more power to Beckham for reaching out to Carter in an effort to better himself.

But why did he find it necessary to work with Carter while the rest of his Giants teammates were in OTAs together, building chemistry for the 2017 season?

Haven’t there been other weeks during this offseason when Beckham could have worked out with Carter so he could be with his teammates at OTAs. The OTA schedule, after all, is not exactly rigorous and intensive like training camp.

Surely, in between the Coachella music festival Beckham attended last month — which led to him being hours late to a youth clinic he had committed to attend at MetLife Stadium thanks to a missed flight — and whatever else he’s been filling his off days with, Beckham could have taken the time to work with Carter when the rest of his team was not working together.

Carter, of course, said he doesn’t see a problem with the poor perception Beckham has created.

“To me, it’s not about the optics,” Carter said. “It’s about a guy that reached out to me three years ago I have a relationship with. And he is among the three best receivers I’ve ever mentored. He is in the same class going into Year 4 as a guy by the name of Randy Moss and Larry Fitzgerald. This kid is freaking phenomenal. The sky is the limit, and I believe in 108 days [at the season opener Sept. 10], the Dallas Cowboys will see that.”

If Beckham performs up to the standard of the superstar he perceives himself to be — against the Cowboys on Sept. 10 and for the rest of the season — then no one will care if he ever attends another OTA for the rest of his life

If he doesn’t, then just like the ill-fated Miami boat trip last winter, his antics will come back to haunt both him and the Giants — Cris Carter’s opinion notwithstanding.
