The talent in Ohio was down the last few years after being incredibly good right after Thad took over. If you go back and look at the rosters of Thad's really good teams, other than Conley, Oden and Turner, you see mostly Ohio kids on there. He's had to go out-of-state and you're not going to win most of those battles. The junior class in Ohio has two studs in Kennard and Bragg and neither is a lock to OSU at this point. That is a little concerning, but if he gets one of the two and then locks down a few in the talented sophomore class (V.J. King), OSU will be just fine.
The other problem is that Ohio hasn't produced a top big men since Sully. The state had a nice string there with Koufus, Mullens (who didn't do a whole lot at OSU) and Sullinger as all 5-star type talents. There hasn't been a whole lot of frontcourt talent in Ohio lately and outside of Bragg there isn't much coming that I know of until maybe this year's freshman class.
