Bradley's deal hasn't been officially announced yet because they can't announce it until the Moratorium's officially over. Until then, even if they've agreed, its all "contract negotiations." Like many other things -- once you understand how a system works, the magical mystery tour leaves town.
Further, I honestly enjoy a good, well thought out piece of conspiracy theory/speculative fiction/etc., but this isn't that. I agree that being civil is a good idea, though.
As I said at the beginning of this thread, I do think its possible that there is a deal, but unlikely. That said, the moratorium doesn't explain much one way or the other. James Young hasn't yet signed a contract, so he can be traded at any time. When he signs his contract, he is ineligible to be traded for 30 days. Furthermore, draft picks signing rookie contracts are the only contracts that are allowed to be signed during the moratorium. So that he hasn't (and Smart hasn't) signed one isn't insignificant. Olynyk signed his last year before summer league, for instance, as did (I think) Sullinger and Melo the year prior. This could be because there's a deal already made. Or this could be because they're still working on a deal and want to keep their options open. Or this could be because they don't want to give the players 120% of their slot value (which the Celtics always have as long as I can remember) so as to keep some salary clear while they make other trades and signings. Or this could be because they're still negotiating the contract, and are waiting for his neck to heal before signing something.
Again, I don't think it's terribly likely that there's any reason other than he's injured, and Occam's razor is probably the rule of thumb here. But the facts are that he hasn't played, he hasn't signed his contract, and that at a minimum, and we know Ainge is still trying to make trades. To think that Young is being held out because of a trade, either agreed to already or in the final stages of negotiations, shouldn't strain credulity all that much so as to be seen as a conspiracy theory.
