I strongly suspect that Sherri would like to have a post: Robeson, or maybe Hillsman. We don't know if Hillsman intends to visit as yet. But, I would be surprised if Sherri wanted two scholarships used.
I think Sherri is probably a lot more comfortable with Williams, Kellogg, and Gibbs than most are. If she were concerned, she could have saved a scholarship for another PF, but she gave it to Gibbs, rather late. That says something. She didn't need to do that. Kellogg is better than folks on this board seem to think.
With Williams, Kellogg, Gibbs, and a post recruit, I think Sherri would be happy with the interior. She can count on Sharane, Maddie, Nicole, and maybe even Gioya and Peyton for rebounds as well.
Sherri has the guards that she wants. With the few remaining scholarships that OU will have for the next couple of years, given that we have so many new recruits, I think Sherri will give scholarships only to some pretty good candidates.
She may sneak someone into the fold, but I think it is an either/or situation.
