In professional football, organizations pay elite quarterbacks millions of dollars per year for their performance.
Despite all that money, that quarterback will still make mistakes every single game.
They will fumble the ball. They will be sacked. They will throw an interception.
Does this mean they are not a valuable player?
On the aggregate, they have been determined to be a great player.
But, everyone makes mistakes. It’s just a part of the human condition. We can optimize for them and learn from them, which is exactly what the pros do.
