Blackshear (Bluffton, S.C./Bluffton) said he gave the news to running backs coach Everette Sands. A 6-foot-4, 235-pound defensive end, Blackshear amassed double-digit offers from programs such as Alabama, Clemson, Florida and Florida State after recording 96 tackles, 18 tackles for loss, five sacks, 15 hurries, a punt block, a field goal block, three fumble recoveries, two defensive touchdowns, two pass deflections, a receiving touchdown and a rushing touchdown during his sophomore season.
He took visits to Florida and Clemson as well, but the Gamecocks won out for his early decision.
"I chose South Carolina because I know I can guide and lead the program when it is my turn," Blackshear said. "South Carolina is a great place to be and I am LOVED all over Columbia."
Blackshear joins wide receiver Dexter Neal (Stone Mountain, Ga./Stephenson) as South Carolina commitments for the 2015 class.
