COLUMBIA — When Kenny Miles visited Marcus Lattimore in the hospital over the weekend, they didn’t talk about football. Instead, they discussed their families and “everyday life,” Miles said. They have been friends and teammates since 2010, when Lattimore arrived at South Carolina as a prodigious true freshman running back and took most of Miles’ carries. In 2009, as a redshirt freshman, Miles was USC’s leading running back with 117 carries for 626 yards. In the next two years, he carried 40 and 54 times. Last season, when Lattimore suffered a season-ending left knee injury in the seventh game, Miles had just 18 carries in the first 11 games as he dealt with a wrist injury that sidelined him for four games.
