I just want to understand how 2 people can love their chosen spectator sport with the exact same intensity but:

Football fan says "we won/lost" after a game.

Tennis fan says "player X won/lost" after a game.

Can someone explain that in a way which is better or more respectful than my explanation? Which is just that football fans are stupid and NEED to feel like they are part of something larger than themselves. And tennis fans have a realistic view of their favorite sport?
