It is interesting that Hayward essentially has no-trade leverage. If I understand correctly, he can't be traded until he opts in. My guess is that the arrangement is that if the Celtics are able to put together a trade that he likes, he opts in and essentially accepts the trade. If he doesn't like the trade, he doesn't opt in and takes his chances on the open market. Maybe he gave a list of teams to the Celtics, that would not surprise me.
Seems reasonable to me and I still don't think there is ill-will or bad feelings. The right trade is a win - win - win for Hayward, the Celtics, and whoever ends up with Hayward. The clock is ticking though, if they are going to get something done, they have until what, 5:00p?
