One very real possibility is that there was no offer for a location that KD wanted to go---so, illustratively, nets said "here's what we've seen" and it was offers from the Knicks, Memphis, and New Orleans (guessing for different reasons KD doesn't want any of them) and KD asked some questions about Miami, Phoenix etc where he wasa interested and they either explained no offer at all (easy to see from Phoenix) or not a realistic one for team (Miami seems likely to end up here), and they then agreed that the demand right now isn't sufficient anywhere he wants to go, and both sides are better off seeing what happens by the trade deadline. KD is losing goodwill by the day PR-wise, so there is some incentive for him to play nice, and I do believe he does not want to sit out...so he is probably going to want to clarify things in next few weeks regardless of where trade talks stand
I still do think a deal is possible pre-season---the spin would be "so and so popped up to our surprise and the offer met our needs as well as KD's best, so we did it" The number of guys in the league for whom the team is legit not even taking discussion calls is really short---GA, LBJ, etc. Even Tatum likely the Celts listen to the offer before saying "no chance". So I don't buy given the history and trade request that KD is in that first group anymore.
