LAS VEGAS — There was a time when Cat Zingano looked at UFC women’s featherweight champion Cris Cyborg as unbeatable, a Brazilian destroyer without weakness. And it’s hard to fault her. Cyborg’s 13-year run of dominance is virtually unparalleled in mixed martial arts. But once Cyborg made her way to the UFC and began regularly competing against Zingano’s fellow bantamweights, Zingano started viewing Cyborg from a different light, a more detached perspective that led her to be one of the few women in the sport actively calling for a chance to test herself against the featherweight queen.
