There is already legal precedent for pro sports teams in different sports having the same name. There is nothing 'proprietary' about 'Warriors'. I doubt there's a single thing Golden State could do legally to stop Dan Snyder from using the name, and I'm skeptical Golden State would care enough to try and make an issue of it. As for it being undesirable because it's already being used - I don't believe that's a significant concern either since it's in an entirely different sport, but some may feel that way.The Golden St. Warriors have moved to solidify their claim to that name and it would be a prolonged and nasty battle for the football team to use it. Warriors is unlikely. Renegades is gaining some steam. That would be a good name.
