Marcus Lattimore

An elite talent at running back, Lattimore fell to the fourth round of the 2013 draft thanks to knee injuries that limited him to just 16 total games in his sophomore and junior years at the University of South Carolina. Despite the injuries, he scored 38 touchdowns in his college career while looking like a legitimate first-round prospect and a well-rounded back. After sitting out all of last year due to his knee, Lattimore's fully healthy and ready to go this season. While the Niners have a crowded depth chart behind aging starter Frank Gore -- Kendall Hunter, LaMichael James and new draftee Carlos Hyde will all fight for the right to tote the ball -- Lattimore has all the skills to float to the top.
