This sounds more like a complaint that the skill shown by the Warriors is so good that no one will be able to replicate it. That doesn’t mean it’s bad for basketball. You wouldn’t say a great singer is bad for music because their voice is too good. And you certainly wouldn’t blame them for someone trying to replicate their music and failing miserably because they aren’t talented enough. Not everyone is on the same tier or has the same skill level. Appreciate the warriors for the things they are able to do. If others try to replicate their style and fail, that’s their own fault for not knowing their own limitations.
