I find it amusing that some posters are worrying so much.
"Reading the tea leaves" as it were is something you can do what you want with. If you want to find reason to be worried you will find it. And vice versa. Sometimes there is reason to worry but we have nothing so far that I have heard about. It is better if the visit not happen for OSU, but at the moment it is not like he goes there and then it is over.
Lots of OSU commits have visited other schools at the end and still committed. For any single example you can think of there are others.
The human mind is focused on remembering negatives or exceptions and ignoring other things.
I don't think anybody is disputing he is a big get or would be a bad loss, but there is nothing out there at the moment other than speculation. If the OSU guys start worrying than worry. Before that, not going to worry. Guys talking to Hartline or other OSU staff are going to be pretty tunned into this and one thinks they must like their chances.
