The only sporty YouTubers I follow are in parkour and World Chase Tag. Most of those are demonstrating their own skills, so they do have to be good at what they do. Some are among the best in the world at what they do. Only one (JimmyTheGiant) is mostly commenting and interviewing (and making brief documentaries about the history of the sport), and he's open that he's not the best at the actual parkour.
