I think there are a number of people here that would prefer not to sign Hayward next offseason, at all, nevermind trade our best prospect and a BKN pick for the right to pay him loads of money. I probably lean toward signing him if Griffin/Durant don't want to to come here (not likely, I know), but it's not the homerun move that we all dream of.
With that in mind, I take both Jaylen and the BKN pick off the table and probably offer something like Rozier and 2018 Bos pick along with Amir. I don't even like the idea of trading Rozier, tbh, but if Danny decides that he wants Hayward and doesn't think he can sign him away from Utah in the off-season, then he is going to have to give up something of value.
Like with Horford, I would much prefer to wait until the offseason and hope for the best. He is not so good that we have to have him, but I wouldn't turn him away, either.
