The football defensive player is not much more autonomous. A coach tells the defense which type of defense to use for each play. On the sidelines, the coach shows them pictures of the other team's recent offensive sets, in case the defense did not fully comprehend it on the field. All the fun and spontaneity is gone from football. Younger fans do not realize it, because all they have ever seen is a team with 10 coaches orchestrating every move on the field.
Someone writes the words they speak.
A director tells them how to deliver the lines. The cameraman tells them how to move and where to stand or face at any given time. They talk inanely about the renovation to their kitchens, or about what they feed their dogs and cats. With no writers, directors, or cinematographers to guide them - they are pretty naked. When I was in law school, I wanted to become an FBI agent.
