It's easy to spot a bandwagon fan. When the team is losing, they are the fans you are looking for because they are nowhere to be found. They're usually the first to jump on the bandwagon and also the first to jump off if things go wrong. Look who is around when the team is 4-12, who is still wearing their gear with pride. It comes down to simple loyalty. Bandwagon fans are only loyal to the winning side.
