Blackshear planned to ride the recruiting process out and to make a decision when he was a senior, but that changed on Tuesday.
"I changed my mind a little," he said about his abrupt decision he made Tuesday afternoon. "South Carolina really wants me and no other school checks on me the way they do. I believe I can be the face of the program early and that is what I want. Columbia is like a second home for me and it is a good fit for me."
He has been to Columbia, S.C. already and he really likes who he could be following at defensive end in their defense.
"I like the coaches and the defensive scheme at South Carolina. Jadeveon Clowney is a special player and the coaches have told me that I could be next for them. Clowney being that top guy helps me with them because I want to be that No. 1 draft pick one day too. I love their overall defense."
