That has to be a little uncomfortable for the Buckeyes. 

On Tuesday night, it may have gotten a lot more uncomfortable. 

That's because Michigan recruiting coordinator Chris Partridge, who used to be the head coach at nearby New Jersey high school Paramus Catholic, may have taken a shot at the Buckeyes about Walker on his public Twitter account.
