Another anemic performance from his offense — even in a victory — has Giants coach Ben McAdoo mulling changes that might start with McAdoo himself.

The first-year Big Blue boss said Monday he will think about surrendering the play-calling duties after the Giants’ season-long struggle to find the end zone continued unabated Sunday in a 17-10 victory over the Rams in London.

Also open to change are both the Giants’ personnel and the scheme itself on offense as part of a bid to shake out of their season-long doldrums on that side of the ball.

“We are going to look at everything,” McAdoo said in a conference call Monday as the 4-3 Giants entered their bye week. “We just had a staff meeting. We’re going to look at personnel, we are going to look at scheme, we are going to look at a bunch of different things, [including] personnel groups to see if we can get it jump-started here over the bye week.”

McAdoo already is feeling the heat to shake up his attack after the Giants mustered just 232 yards and one offensive touchdown against Los Angeles, a performance that caused them to fall to 25th in the NFL in scoring and 20th in total offense.

It was the third time in seven games this season that Eli Manning failed to throw a scoring pass, despite boasting a star-laden receiving corps of Odell Beckham Jr. and Victor Cruz and standout rookie Sterling Shepard.

The running game was even more inept, mustering a mere 36 yards on a Rams defense that has been middling against the run all season. The Giants are now last in the league in rushing and have rushed for more than 78 yards in a game just twice all season.

The run has been so lacking that the Giants have gone almost exclusively to a three-receiver lineup in recent weeks, but McAdoo said he will “go back to the drawing board” during the bye to bring back more balance.

“We need to get the run game going,” McAdoo said. “With the way the game went, they tried to cover everyone up, cover the core up, use some line movement up front, and we had some big play opportunities in the run game [but didn’t convert]. It’s a challenge to be consistent when you are getting those looks, but you need to cash in on those big-play opportunities.”

The first position on offense likely to get a shakeup, though, is tight end. McAdoo reacted to Larry Donnell’s early fumble against the Rams by saying he will give Jerell Adams and Will Tye more snaps in order to push Donnell.

“Whoever is playing the best is who we will go with,” said McAdoo, whose team returns to action Nov. 6 against the Eagles at MetLife Stadium — the first of three consecutive home games for the Giants.

McAdoo has called the plays since coming from the Packers in 2014 to be Tom Coughlin’s offensive coordinator. He hired Mike Sullivan to be the offensive coordinator upon being named to replace Coughlin but kept the play-calling duties.

Despite leaving himself open to the idea, McAdoo still seems unlikely to abandon the play-calling job. He is a disciple of Green Bay coach Mike McCarthy and watched McCarthy give up play-calling duties under public pressure last year, only to take back the job later in the season.

Even so, McAdoo admitted he is at least open to the possibility of letting Sullivan handle the plays.

“Everything is on the table,” McAdoo said. “Everybody in the building wants to win, and we have to do what’s best for the team. Whatever we have to do that’s best for the team, we’ll take a look at.”
