Of course there are frivolous grievances, and this is a perfect example. As I’ve noted at other times, you are absolutely entitled to your point of view. But so are others entitled to theirs, and mine is unshakable that whatever it’s called and through whatever means it’s being brought, this is a frivolous claim.
In this discussion I’m using “frivolous” as a legal term, not a subjective one. My point is that this claim cannot be dismissed as a frivolous one in the NFL’s grievance arbitration process the way a lawsuit in civil court can be. The NFL and a former player who is now a professional malcontent can waste all the time and money they want in their own internal proceedings.
