If the NBA truly has a restriction on how many teams can use Black uniforms, and if some teams in the last few years have tried to go to Black, or back to Black as rumored and have been turned down because of this restriction, and then Oklahoma gets to use Black then yes, it's pandering to them.
The NBA would be bending the rule, because a team moved, is changing their uniform, and wants to use Black, because it represents oil. The answer should be (if there is a restriction) I understand why you want to use the color Black, but we have turned down other teams in the last few years for going back to Black or changing to Black. Approving your uniform would not be fair to them. We believe having too many teams with the color Black is not a good thing, therefore we can not approve your new unfiorm.
