how the forget does a person become a fan of a sports team anyways? do they like the fact they they win? do they like the logo? are they a half-cousin to one person on the team?? i dont understand
Often people support a team local to them, or they pick up the team their family or friends support.
Then there are people who are fans of specific players and they follow them as they change teams.
There are people who start following a team after they have some entertaining/impressive games also.
And you get the glory-chasers who jump onto a team as soon as they win big, just so they can boast to others that their team won.
There are a lot of ways to start supporting a team or to change your support.
There's no real right or wrong reason for supporting a team, but it's generally considered dishonest if you suddenly start to support a team who becomes big, and if you drop support as soon as your team has a bad streak.
