This really worried me. There's no reason for him to consider Washington over Boston unless more talent is going to Washington. I'm worried Durant is secretly considering going to Washington and Horford is considering following him.
Just like the Thunder, they'd have to dump Gortat and somebody else to make the money work. Unlike the Thunder, that would not leave them with a functional team.
After Beal's deal, they'd have to do that to get just one of them, right? They certainly don't have the money to pay Durant AND Beal AND Horford, iirc.
Either way, it's well-known that Durant has no interest in going back and playing there, which is why they didn't even get a meeting. So there's nothing to worry about here.
