Moss also volunteered to be a mentor for Winston, and said he'd tell the reigning Heisman Trophy winner, "if you need someone, reach out to me."
"He's still a young man. You have the people from the National Football League, and he's still on the baseball field, too. So there are a lot of professional people who are really looking at him, and seeing if he can come and lead a professional team," Moss said on Fox Sports. "(It's) the 'no' people. He needs the 'no' people in his camp. Sometimes people get in your life for the wrong reasons."
Winston currently faces a disciplinary hearing at Florida State for an alleged sexual assault from 2012. The hearing, which will determine whether he violated the university's code of conduct, was recently postponed to Dec. 2.
Earlier this season, Winston was suspended one game for yelling an obscene phrase in Florida State's student union.
Moss spent one redshirt season in Tallahassee while in college before transferring to Marshall, and said he understands the situation Winston is in.
"I like Jameis Winston, I went to Florida State, so I know some of the things he's going through as far as the hype and magnitude of where he's at," Moss said. "Those no people, what I mean is, those people to be able to tell him no."
The Seminoles (10-0) host Boston College (6-4) on Saturday.
