That he, as one of the best players in the NBA, signed with the best team record wise in NBA history who were highly favored to win the championship without him, and right after they beat him in the WCF. It’s the equivalent of MJ signing with the Pistons after they beat him or Kobe signing with the Spurs after they lost.
We are fans and we don’t really care if it was the best decision for him. The NBA is entertainment, and we all grew up watching players compete. To watch one of the best players sign with his competition just cause he ‘likes the way they play’ is like NBA malpractice. It’s offensive to me as a fan. I really don’t care what is best for Durant. He’s fine to sign wherever he wants, but he will be criticized for making this particular decision and rightly so.
