Ex-South Carolina football star Marcus Lattimore says he's got two of the best mentors EVER to help him on his new journey as a high school football coach -- Jim Harbaugh and Steve Spurrier.
Lattimore's story is pretty famous ... he was a STUD running back in college -- but was forced to retire from the NFL at age 23 after suffering several devastating injuries.
Now, he's taken the head coaching job at Heathwood Hall high school in South Carolina -- and says he's modeling his coaching style after his 2 former coaches.
