Offensive lineman Quincy McKinney (6-4 295) of Columbus, Ga., committed Wednesday morning to South Carolina.
McKinney, who was recruited to USC by Lorenzo Ward, picked the Gamecocks over offers from Nebraska, Michigan State, Southern Miss, Mississippi State, Duke, Georgia Tech, Vanderbilt and Memphis.
McKinney attended USC's camp in July and was impressed with what he saw.
"South Carolina's facilities are beautiful, state of the art, the best I've seen," McKinney said then.
Never miss a local story.
McKinney plays offensive tackle for coach Dale McGee.
"He has great feet and a great motor," McGee said. "He knows how to finish."
McKinney is the 15th commitment for USC's 2011 class and the third for the offensive line.
