The University of South Carolina added another offensive lineman to its class last week, and also dropped one. Du'Van Milsap (6-5, 300) of Buford, Ga., committed over Oklahoma State and Ole Miss. He also had offers from Clemson, Mississippi State, Louisville and East Carolina. "It's closer to home and it just felt like a better fit," Milsap said. While Milsap will be joining the large group of offensive linemen coming in next season, long-time commitment Elliot Williams of Georgia Military Junior College will not. Williams signed with the Gamecocks in 2008, but didn't qualify, and he hasn't made enough academic progress to be resigned. If he returns to GMA next season, USC will re-evaluate him. Calhoun County offensive lineman Eric Mack, another USC commitment, has taken an official visit to Auburn and will visit Clemson on Friday. Mack also will set official visits with USC and Kentucky. He was at the USC-Vanderbilt game and will return to Columbia for the final two home games.
