Renouncing Barnes is mostly a formality. The effect is the same as not matching his offer sheet. This just spares Barnes and Dallas any delays.
However, the Mavericks surely factored Barnes’ restricted status into their offer. They wanted to give Golden State more trouble. Would they dare lower Barnes’ offer — unofficial until the moratorium ends — now that he’s unrestricted? It’d violate the NBA’s unofficial code that governs all early-July deals, but DeAndre Jordan did it to them last year. If I were Barnes, I’d want to find out Dallas’ intentions before other options dry up.
Bogut would fit well with the Mavericks, who badly need a center. His defense would help protect Dirk Nowitzki.
Golden State could have other suitors for Bogut, too. If one team offers more than the rest, the Warriors would have trouble turning that down. But if everyone just wants to take him as a salary dump, Bogut might get to pick his preference.
