Have to concur with Ryan here. Vols are in it for some top cornerbacks, and while I love Shelley as a playmaker he is not near as physically ready as some of the other targets on their board. This is where twitter puts colleges in a tough situation publicly. They obviously like Shelley and have to make a tough decision whether or not to take him now or not.
BTW I thought I rated Shelley long time ago but it must have not updated in system. It should be on his timeline now and will update on his profile soon.
