I believe the term used by psychologists is Emotional Over-Identification. The team's performance is personal.
It has elements of strong social identification and hierarchy, vicarious achievement, a desire for control and an affinity for drama. When viewed through this lens, the story shifts from obnoxious to sad and a bit concerning. They are probably at least partially aware of these destructive tendencies, but it's not enough to break the cycle because of the dopamine rushes they get out of it. It's too bad because they seem very knowledgeable and are clearly passionate.
