Saquon Barkley is “numb” right now, but the potential for his feelings to shift to anger lurks around the corner.

Giants general manager Joe Schoen said Monday that the possibility of using a second franchise tag to keep Barkley in 2024 is “a tool we have at our disposal.”

Barkley hopes that the Giants either offer a “fair” multiyear contract extension or let him test free agency, but he learned last year that the tag — a one-year, $12.1 million contract — can be dangled over his head as negotiation leverage.

“They did it last year,” Barkley said in a hushed tone. “So, I’m numb to it. I really have no feelings toward that at all. If you are going to do it, just don’t wait until March 5. Let’s get it over with. If not, let me go. Simple.”

The Giants met with their unrestricted free agents as a group, foregoing individual exit meetings as players cleared out their lockers after finishing a 6-11 season.

So, Barkley didn’t have the “shoot me straight” conversation with Schoen that he previously expressed a desire for so that the two sides can avoid repeating the dragged-out, tense negotiation that ended in July when Barkley rejected a three-year contract worth about $11 million per year, including $22 million to $23 million guaranteed.

“His office is open so anyone can go up there and talk to him,” said Barkley, who wasn’t planning to initiate the conversation. “I went through the whole process last year. We talked more than enough last year, to be honest. Not just [with] Joe.”

The Giants are expected to have about $37 million in salary-cap space, per spotrac.com, so they could manage the tag.

But paying Barkley $22.2 million over two seasons seems like odd accounting when they likely could have had him before this season for about $24 million guaranteed, with the ability to spread it over the cap for three years.

Six NFL running backs have multiyear deals worth at least $12 million per year, and the most recent went to the Colts’ Jonathan Taylor (three years, $42 million, $26.5 million guaranteed).

Barkley could have played hardball with the Giants last summer and not signed the tag, holding out from training camp until they agreed to eliminate the possibility of a second franchise tag from his contract.

Instead he agreed to $900,000 in incentives (that went unearned) and did not miss a practice out of respect to his teammates.

“When we redid his deal before he came to camp, that [tag] wasn’t taken out of that deal,” Schoen said. “That’s an option we have on the table. We’ll have those conversations. I’m not saying we will or we won’t.”

Monday was the first day that the Giants and Barkley could talk contracts under NFL rules for franchise-tagged players.

“They know how to get in contact with me,” Barkley said. “If a conversation needs to be had, it’s not hard.”

Barkley, 27, scored 10 of the Giants’ 25 offensive touchdowns and led the way with 1,242 yards from scrimmage. But he missed games due to injury [three] for the fourth time in six years.

“I think there are offensive weapons,” Schoen said of the roster. “It’s just a matter of being consistent.”
