As noted in the diary by eddiethealbinosquirrel (What kind of fan are you?) I was thinking along the same lines as it relates to professional sports.
Thus, a poll of my own to find out how you decide to cheer for the professional team(s) you do. Obviously the reasons may vary depending upon the sport, so we'll stick to football for now, as I believe it's the most widely followed.
How did you decide to follow the NFL team you call your own?
Hometown Heroes (live or lived in the city or very close by) (80 votes)
Rivals (cheer for the team that hates the team you do) (1 vote)
Players (cheer for certain players, to hell with the teams) (51 votes)
Uniforms (dig the unis and thus, the team) (3 votes)
Style of Play (love the schemes and sets used) (2 votes)
Coaches (following the leader of the team) (1 vote)
Regional (follow the closest team within a few hundred miles) (14 votes)
Some other reason not listed (15 votes)
