Re: Shaq and JO..
1.) Shaq is not injured. His *injuries* are that he's 39 years old and that he's, well, Shaq, and thus entitled to take an inter-season vacation if he feels like it.
2.) There are indictaions coming from within the organization that JO will be ready for the playoffs. They are holding him back because there's no real reason to bring him back just yet (while they work in all the new guys) and to give him as much time as possible.
Hope that helps.
