"I think he's the future of the NFL," Vick said of last year's Heisman Trophy winner, according to NJ.com.
"I've been around so long, I appreciate guys coming out of college. I look forward to watching him. I have high expectations for him."
Vick, 34, broke into the league as an athletic wonder with the Atlanta Falcons before being sent to federal prison for his involvement in a dog-fighting ring that cost him nearly two years of his life and three seasons in the NFL.
With that history, Vick can somewhat relate to the off-field concerns surrounding Winston.
"I think he, over time, has made some poor decisions," Vick said of Winston. "Have I been there to know exactly what happened? No.
"But I do know one thing: He may make some poor decisions, but he gets on that football field and he plays his ass off. Yeah, he can mature. He'll mature. I see him maturing as time goes on. Like, this year hasn't been as bad of a year as the first year was for Jameis. I think the kid will continue to improve."
