Maybe a person who is obsessed with a sport like baseball, having a deep understanding of the game's rules as well as various game statistics, yet they wouldn't be caught dead playing softball with their company's team, despite their knowledge, that would likely fly out the window once they were put on the spot and expected to perform in an intense, in-the-moment competitive physical environment.
Someone content to fantasize about being a driver in a film like Bullit or Drive, but they would probably be the last person to actually end up in that role.
