1.) The landscape of the entire league is set to dramatically change. The FA class that summer is potentially ridiculous--even more ridiculous than 2010. And the new luxury tax penalties are set to kick in and a lot of teams are going to have to radically change their rosters and the way they do business to avoid the new tax. It's pretty crippling.
2.) The Wall/Beal era will hopefully be stable enough for them the weather a change as significant as a new GM and FO being installed. Making big changes at this point when Wall's career is in such a fragile place and Beal is just a rookie could completely stunt them. Hell a new GM could have come in here and immediately started trading everyone. I think Ted believes there is a worthwhile core to be had here. And as far as Wall and Beal, I still agree they are worth building around.
Everyone else could be dealt though. Ted probably still thinks Nene, Crawf, Booker, Ves, Singleton, and Seraphin are untouchable and that they're as much a part of the core as Wall and Beal. I think that's a big error in judgement and I'm thinking that will be settled by 2014 one way or another.
