In all seriousness, Shaw brought MMA to the full mainstream. No doubt he damages the overall reputation w/ the WWF/WWE like feel [i.e. Baroni entrance] and the ultimate exposure of a "superstar" in Kimbo, but Gina Carano became a household name and helped bring true legitimacy to an otherwise contained sport.
I.e. My Dad called me about the fights.
You have to give credit where credit is due. No doubt Dana and the UFC are the big dogs and have made mountains out of molehills, but Shaw pushed it past the peak and had at least laid the foundation for its ultimate mainstream legitimacy.
