Mind you, I believe this mostly on instinct, not because Danny says it. In the same presser he said that we won't tank because "this is the Celtics" - completely ignoring that the Celtics have not only tanked, but have tanked with DANNY AINGE AS GM.
Not according to Danny Ainge, we didn't

Danny denying tanking is meaningless; is he supposed to say, "Yup, suck city this year. We're colluding with the coaching staff and players to intentionally water down the quality of our product to game the system for a better draft pick. All our fans, and especially our very powerful commish, who absolutely hates feeling shown up in the media, is on his way out, and has nothing to lose can just deal with it."
Danny saying that we're not pursuing any major free agents (and media reports so far corroborating it) was a lot more informative about our priorities than denying something he has to deny.
I do think we'll hang onto Rondo unless we get a strong offer for him. But if we do get that strong offer he's donezo.
