Jamie, what your list tells me is that kids from Glenville either go to OSU, or to a clearly inferior schoool (sans UT and Miami, but did Latwan have an OSU offer? He wasn't a real Glenville kid anyway, he only played there his senior year). I'd be willing to bet that almost all of the kids who went to the schools you listed did not have an OSU offer.
So maybe it's not that "all Glenville kids go to OSU" but more like "all Glenville kids go to OSU who have that as an option." And this kid has that as an option.
That said, our other boy at Glenville (Cardale something?) does not have an OSU offer, and probably won't get one to play QB. That is a much more likely option.
