We all know Royce isn't a diva, because we all know of personal stories about him stopping for pics with people's children, shaking hands, etc. Royce knew he had our support, and he reacted in kind.
NBA fans don't have that quasi-personal relationship with him. They don't know who he is or care what he does after a game - they want him to perform. They just don't care about his platform - not yet, anyway, and he isn't endearing himself to them.
He is hurting his own cause, both literally and figuratively. He is hurting his career, but he is also making it look like anxiety sufferers are high-maintenance prima donnas - and he is anything but that. I do NOT advocate for him hurtin his health, but he also has to make some concessions.
MAI adore Royce, I hope this works out.
