Substitutionary Virtue?

If you're a fan of a sports team it's because you have some sort of connection with that team. You identify with the team by geography, or maybe you identify with the team by your participation in what the team represents ie. high School or a college you attended.

You identify with the team in some way. Like by sport; I'm a Packers fan, by school; I'm an Notre Dame fan. You cheer on your team and praise the virtues of particular athletes and their team. You feel good when your team wins. I might say you rejoice when they win, because they earned it. Hard work, teamwork, dedication and stick-to-itiveness. 

Commendable virtues applied and the victory gained. 

You rejoice and feel good? Because your team won. As though their victory was your victory? Isn't that weird?
