Justin Tuck isn’t a general manager — not yet anyway, though he is set to graduate from the Wharton School in May — but he knows what he would do with the Giants’ No. 2 draft pick.

And it doesn’t include a quarterback.

“If I’m just going to go out and say it, I like [Saquon] Barkley,” the former Giants defensive end said Tuesday at the Park Hyatt in Manhattan, where he was announced as the head of the board of advisers for the new Alliance of American Football league. “He gives them so many options as a third-down back, as a guy that can take a lot of pressure off of the O-line, make guys miss, but also added value in the pass game for Eli [Manning] out of the backfield. A New York product. I think he is the most dynamic player in the draft right now.”

If he’s available, that is. The Browns could nab Barkley, the physical specimen and former Penn State running back, with the top pick.

Even if they do, though, Tuck isn’t giving up on the 37-year-old Manning just yet, believing he has multiple years left in him.

“Every time something has happened to make people doubt Eli or question his ability, he’s come back in a really, really big fashion,” Tuck said, citing the unique vantage point he had as the QB’s teammate for nine years. “The more people say he can’t do something or he’s done this and he’ll never do it again, the more I bet on him. He’s definitely a guy I would watch for as Comeback Player of the Year next year.”
