While I liked your comment enough to upvote, I then realized that Chairman isn't an operational position. It's more a position where the person can exercise ownership of a company (to put it in layman terms). In your analogy he wouldn't be the athlete, more like the person who gets the winning money (assuming his son also has shares) and chooses the trainer/coach of the athletes (which still needs skill btw).
Warren was CEO until 9 months ago. While yes, he's been chairman for 50 years, he's been an exclusive chairman for only 9 months. The role is ambiguous anyways and it's pretty obvious that someone else won't have the authority Warren has. And his son has been a director for 30 years so it's not like he's a new hire
He was chairman and CEO for a long time. Since he has only been a chairman for not that long I don't think it's fair to say that he's been a very active chairman for a long time.
