On C. J. McCollum's podcast (didn't know he had one) Sunday, he mentioned that among players' conversations that Toronto is the team most likely to trade a player before the deadline. He mentioned, while saying specifically that he can't mention a name because of tampering restrictions, that there are some players in Toronto who are complaining/whining, whatever, and that they are the one(s) most likely to be moved over any other player in the league before the trade deadline.
I do believe that with any of the players that McCollum could be referring to, that it will take three teams involved in the deal to get it done because of the difficulty of Toronto's situations with all of their contracts of the players likely to be moved.
