Heh, less dominant or not, almost every event that involves a Gracie there's always a "holy crap this guy is a Gracie, he's lethal" comment from the commentators.
Speaking of which, does it always seem like Joe Rogan likes to exaggerate? Comments like "world class wrestler", "lethal ground game", etc.
It's the commentator's job to paint a vivid and exciting verbal picture. If he weren't doing the job, he wouldn't be allowed to continue doing the job.
