I think that Danny Ainge will be very busy at the deadline this year with alot of expiring contracts. You will see lots of contenders look to get many pieces from the Celtics.Bass,Thorton, Anthony and we all know than Rondo could be dealt as well as Uncle Jeff Green. Unlike this past year when we did nothing that deadline day. I say he makes 3 trades.
I think you're right that Danny will be fielding a bunch of calls this year. With Bron moving to Cleveland and Miami no longer perceived as an insurmountable team, there'll be more teams that think they have a shot at it this year. Celtics have several good role players that could be attractive to other teams looking for one last piece to get them over the top.
Green, Bass and Thornton would seem to be the prime targets for a deadline deal with AB and Turner next in line. Each is a solid role player that could step in as a starter for whomever acquires them.
The question becomes what would Danny take in exchange since all are on short deals except AB. I could see Danny taking on a non-performing player on an expiring deal with a pick in exchange for any of those guys except maybe AB who'd have to have a slightly better return. Can't see Danny taking on a player with another year on their contract unless he sees a chance to use that player as salary balance in a deal in the 2015 offseason (which is Wallace's only value right now).
I'd be surprised if Danny doesn't make at least one deal at the deadline. 3 seems a bit high though
