For someone who seemed to be a Buckeye lean for a while, this is an interesting development. He must have had a good enough visit to South Bend over the weekend to get a response from Bartow, Gleitman, Anbender, and Loy.

I'm hoping this means high OSU staff confidence on other DL targets (Tufele and Young, in particular) for him to start looking/leaning elsewhere. Maybe it doesn't, but either way, watching how this class finishes is going to be a lot of fun.
