Yeah so I said on the GB, I'm really confused about this given that Kyrie just opted-in.
Possibilities I see:
1. KD & Kyrie looking to be shipped as a package deal, which required Kyrie to be under contract...but the combined salary of the two players to me seems like it would be too larger for any other team to be able to match.
2. KD looking to Nets & Kyrie...but why wait until Kyrie opted in?
3. Reporting timeline is confused and KD actually issued the trade demand privately before Kyrie opted in, and either does not actually want a trade now, or all parties agreed to keep KD's trade demand secret until Kyrie's situation was taken care of...but I'm not sure why that made sense for all parties.
Forgetting about where we are at the moment, it seems plausible that when the Nets refused to max extend Kyrie, KD decided he wanted out and the only way to save that was if negotiations ended up getting Kyrie a multi-year deal...but again, that implies that KD really wanted to keep playing with Kyrie, and if KD really wants to play with Kyrie he's literally on the same team with him right now.
Coming in from the Nets perspective, assuming the trade demand is real and still live, while I'd be disappointed that KD wanted to leave, I think I'd feel a bit relieved at the current timing. If you had to trade Kyrie first, then there's all sorts of worries about what would be acceptable to KD. With the focus being on KD, nothing else really matters, and you do have him under contract.
I'd basically tell the rest of the NBA: Bring the bidding war. Once KD was traded, then you can figure out what to do with the lame duck Kyrie who has much less value but (previously) had more likelihood of causing chaos for reasons that made no practical sense for anyone, himself included.
