It is not uncommon for men and women who have excelled at a game to continue to be influential as administrators in the sport of their choice.
But it is difficult to think of one who had a greater impact in so many ways as Richie Benaud, who has died, aged 84.
Cricket would be much different today were it not for his influence as a captain of Australia, his central role in the World Series Cricket revolution, and his authoritative television commentary.
In each sphere, Benaud was virtually without peer. As a player, he was the first to score 2000 test runs, and to take 200 test wickets through his mastery of the difficult art of leg spin.
