Tony Jefferson’s best friends told him to stay retired.

If Jefferson was seeking brutal honesty from his inner circle in Feb. 2024 as he considered returning to play in the NFL — after spending one year as a pro scouting intern with the Ravens — the former Giants safety got it in bunches.

“I went back home and started training, and I was like, ‘Am I really going to do this?’” Jefferson recently told The Post from his spot in the Chargers locker room. “All my friends were like, ‘Don’t do it. You’re washed. Leave it alone. Your playing days are over.’ These are my former teammates. But I believed in myself.”

It’s likely no NFL player has endured more of an emotional roller coaster over the past two weeks than Jefferson.
