With the news of Gillispie being out at UK, there's a possibility Ferguson may reopen his recruitment. I have no idea what
OSU may be looking to do with any additional 'ships that may open up for 2010. I've heard they're looking at some PG's but I believe they are also still recruiting Adreian Payne. Ferguson could be an option if they want another big and Payne decides to go elsewhere.
