I’ll keep it brief today. The best golfers in the world are usually in the running, but who wins depends on who flips heads on the most coins i.e. who makes the most putts. Putting is a skill to be sure, but there is enough chaos in the green that randomness has a heavy say in who wins. Skill can wholly dominate when the differences between the best and everyone else is greater than multiple standard deviations of a coldly binomial distribution.
The greatest record in golf is not who won the most tournaments, but Tiger Woods making 142 consecutive cuts after the first two days of tournaments. He was so much better than everyone else that even when every coin flip went against him he was still in the top half of the leaderboard. The greatest record in tennis is Roger Federer making 23 consecutive semifinals in major tournaments. The greatest record in the NBA may be Lebron James reaching the NBA finals 8 times in a row, including with some Cleveland teams exceedingly thin on talent. The home run record is nice, but Barry Bonds greatest achievement may be his reaching base 61% of at-bats in 2004. 61%! To put that in context, the leader last year reached base 42.5% of the time.
The mark of true excellence is when repeated competition reveals a gap from their opposition so great that even the cruel left tail of randomness can rarely overcome it.
