Ex-NFL Star Fred Taylor -- I Wanna Mentor Laremy Tunsil (VIDEO)

Fred Taylor says he can save Laremy Tunsil ... with the ex-Jacksonville Jaguars running back telling TMZ Sports he wants to mentor the embattled NFL rookie so he doesn't become the next Manziel.

Taylor spent 10 years with the Jags -- and was inducted into the team's ring of honor ... and after the Tunsil drama at the draft Thursday night, he told us he wants to help the kid.

"I just reached out to some of my people to see if they knew him," Taylor told us ... "I'd like to mentor him. I'm 10 minutes from the Dolphins facility."

Taylor said playing South Beach can be tough for young players -- but he thinks with the right guidance, Tunsil can be an All-Pro in 2 years.
