He may have been held back because he was not good enough to play varsity or at least was not good enough to be a starting QB on varsity. They may have wanted him to keep getting QB reps that would have been unavailable on varsity. I do know for certain he was unable to dominate mediocre JV competition. Definitely was not on the level with the varsity QB.   

All I need to know is they are a family of attorneys and politicians.......

Who would hold him back because of "who he is"? And why would they do that? 

One of the better catches you will see to save Clemson’s season         

I would say they’re democrat implants but no one is throwing Molotov cocktails.
