Sure, Eli Manning has seen the recent videos of his top targets — Odell Beckham Jr., Sterling Shepard, Evan Engram, Roger Lewis and rookie Saquon Barkley — cutting, running, leaping and catching passes in the sun, working together out west at UCLA. And, of course, Manning noticed something about all his younger teammates as they showed off their skills and their toned physiques.

They were all shirtless.

“Always,” Manning said, smiling.

It is a sight that pleases the 37-year-old quarterback — not necessarily the bare-chested part, but rather the work ethic on display two weeks before the start of training camp.

“Those guys always work,” Manning said. “Appreciate the work.”

Of course, Manning could not leave it there.

“I know they’ll have to make some adjustments, we do practice with our shirts on with the Giants,” Manning said Tuesday morning at the Offense-Defense Football Camp at Kean University in Union, N.J., taking a playful jab at players more than 10 years his junior. “Friction and all that, they’ll have to make an adjustment the first two weeks, so it might be something new for ‘em, might take a little time for them to get used to that. Besides that, I think it’s great those guys are together, they’re challenging each other and they’re getting excited for the upcoming season.”

Manning is excited, too, as he heads into his 15th NFL training camp with the Giants with plenty to prove and, seemingly, weapons galore to get the ball to — with, at long last, a credible offensive line to protect him. Manning, as a spokesman for the Gatorade Beat the Heat program, spoke to the campers about proper hydration, then tossed some passes to the kids. It will not be long before those passes have more zip on them as he fires the ball to Beckham, Barkley and all the others.

“Always excited for the start of a new season,” Manning said. “That’s a great thing about football, what you did last year doesn’t matter, whether good or bad, it’s all about what you can do this year. Excited about the guys that we have and the new coaches. Been texting with the guys, and everyone’s excited to get rolling and see what we can do this year.

“It’s still an excitement. Kind of prove to yourself you should still be doing this, I look forward to it. Work hard all summer to get ready for the upcoming season, get ready for training camp. I know I can still perform at a high level and play great football and win a lot of football games.”

Clearly, the new Giants regime of general manager Dave Gettleman and head coach Pat Shurmur feels the same way, not only issuing a strong vote of confidence in Manning but also fortifying the offense around the veteran quarterback. They eschewed a quarterback with the No. 2 pick in the draft for Barkley, a gifted run-pass threat at running back, and starkly upgraded the offensive line by signing Nate Solder at left tackle and selecting Will Hernandez in the second round of the draft to move in at left guard.

The entire team reports to camp July 25, but the quarterbacks (Manning, Davis Webb and rookie Kyle Lauletta), select veterans and all the rookies arrive July 22 for a refresher course.

“That’s a first for me, which I think will be good, looking forward to it,” Manning said. “Obviously with a new offense, new terminology, kind of get there a few days early and get the mind work in the right way. Get all your calls down and kinda get a little introduction to that again and get everything refreshed. Looking forward to getting in there and getting a little jump-start.”

Training camp, Manning said, “is never old hat.” The Giants are coming off a 3-13 season, triggering the firings of coach Ben McAdoo and general manager Jerry Reese. Rather than getting swept up and discarded, Manning remains the face of the franchise, not yet ceding that mantle to Beckham or Barkley, shirtless or otherwise.

“It’s probably different for a quarterback than an offensive lineman, I like going into summer camp and doing this,” Manning said. “It’s competitive, it gets you excited about the upcoming season. You get with some young guys, you can be a teacher and teach them, get them caught up to speed. I look forward to it. I went to summer camp when I was a kid when I was 10 years old for the first time, doing it at 37, so I enjoy it.’’
