I thought rules only apply when you are over the cap and using various trade provisions to make the deal work.
@Capt. Factorial help
The typical rule is that if you acquire a player in trade, you cannot trade that player
in a trade that aggregates that player's salary for two months. However, you can trade the player by themselves at any time. Some multi-player trades are actually technically worked out as multiple smaller trades for various purposes (some of these include sneakily creating traded player exceptions), but they are typically never reported that way in the media. So you can see a player get traded before the two-month deadline in a trade where other players go out with him, and you might think it broke the rule but that usually just means the trade was really multiple trades, and his salary wasn't technically aggregated.
BUT
It appears that between getting rid of CoJo and Bjelica, we actually slid down far enough below the salary cap to absorb TT's contract into cap space (if the final form of the trade is simply Delon/TT for us). Players whose salaries were absorbed into cap space (rather than required an exception to acquire) do not have that restriction. If I read the CBA correctly, and I don't have salary cap numbers wrong, we would be able to flip TT in a salary-aggregated trade immediately.
