Injured South Carolina running back Marcus Lattimore is finished with college football. How long it takes the Gamecocks junior to make his NFL debut is anyone’s guess. Lattimore announced Wednesday he was giving up his final season to enter the NFL draft. He was considered a can’t-miss, first-round talent after his first two seasons. However, a horrifying right knee injury in October has dropped his draft stock, and it is unclear when Lattimore might return to action.
