You know, I haven't seen anything that says Brown has been offered by OSU besides the mention in the OP, but it may be the case none the less. If he was offered by rhe Buckeyes I would be surprised if the offer wasn't commitable. They currently have 2 DTs committed in a class in which they have already are stating to turn away from highly rated 4 and Maybe 5 Star prospects because of the numbers. To offer at this point in time means that the coaches really like what they see.
He's confirmed the offer to both Rivals and 247. I believe also to Scout, but I ended my subscription there when Medline ran the site into the ground and no new content was being posted. (InsideNU is a group of students that mostly just parrot information from others when it comes to recruiting.). If he doesn't actually have an OSU offer, it would be a tremendous breakdown in communication.
