10 second call by C

[M&M Guy]

Ok, I'm confused. I have never seen a C call the 10-sec. count; I have always considered that the T's call, since they have the count. In NFHS, isn't there even something in the book about not using the clock for the count, and that it should be the official's count alone? Is this a different mechanic in NCAA? Do you use the shot clock to help determine a 10-sec. violation? What if the shot clock started early and the T is at "8" in his count? (Granted, I'm a little more familiar with NCAA-W, so I don't pay attention to those trivial little items like 10-second counts... )
