I agree that some, if not all of our scholarship substitutes would probably good enough to get a full ride at SC State.
But, I also see many instances of kids who are fine athletes and good enough to play for Clemson going to places like SC State because of academics. These guys are not only very good players, but they have a chip on their shoulders on game day.
A good recent example is former Clemson commit Javarius Leamon (left tackle, 6-7 310, redshirt freshman).
Also, when Clemson's 2nd and 3rd stringers get into the game (as a unit) against the starters from a school like SC State, many times, the cohesion and experience is not there even though the raw athletic talent is superior ... resulting in ragged play and giving up points.
