I can't see any indication of a fair catch or any attempt to catch the ball by the Clemson player.It seems as though the SC player attempted a fair catch signal. It may not have been an effective signal but it shows that he was coached as to what to do in this situation.
Clemson seems to have been given the opportunity to call a FC and receive it. I don't see any attempt on their part to do so.As Lar points out it doesn't matter if he calls for a fair catch or not every person on the receiving team in a position to catch the ball has to be given that opportunity to do so. The kickoff team has to give the receiver room
