To the contrary, I think almost all high school football players in South Carolina are big college football fans.
I also think that almost every one of them that grew up in the Palmetto state has a definite favorite between Clemson and SCAR.
Now, when it comes time to choose a college where they will play, if they are a high enough profile recruit, they may be swayed by a big name school out of state.
But if they have offers from both Clemson and SCAR and they want to stay in state to play in college, there is little doubt in my mind that they are going to choose their favorite from growing up.
I don't believe more than a very slight percentage of HS players grow up in this state exposed to the rivalry and are still honestly "on the fence" when NSD arrives.
