I don't buy any of the rumors one way or the other. I don't think it's a solid assumption that Kyrie is automatically following Durant, it's not like they're lifelong buds. I could see Durant going to LA, but then Kyrie going to NY or Brooklyn. He's a weird dude, and predicting what he will do for certain is a fool's errand.
But I do think Wyc's comments (or lack thereof) the other day lead me to believe that he just wants to blow the whole thing up. Meaning bring back Tatum, Smart & Brown and jettison most everyone else. You'd have to think that if Kyrie leaves and there's no trade for AD (or some other star), Al will leave also. We're probably stuck with Hayward for at least another year.
You have to wonder if Brad and Danny are here much longer. Brad seemed miserable IMO, and I don't think he'd want to come back and coach last year's team again, he seemed much happier and relaxed when we had a bunch of overachieving misfits. And not that Danny is in danger of being fired, but if Kyrie leaves and AD isn't a possibility, does a guy that's accomplished all he has (and who has health issues) want to once again try to start building a team? I think he may very well retire soon.
