I've had arguments with friends of mine (who don't root for the same team as me) over which of our favorite squads has better fans. It's an argument that a lot of people have had, but one that doesn't have a definite answer.
I've looked at attendance stats over the past five seasons (current season included) and tried to figure out which teams do, in fact, have the best fans.
I judged the attendance portion of my rankings based on percentage of the stadium filled as opposed to average attendance. The reason being that teams with large stadiums obviously have large average attendances, but there are a bunch of empty seats. I feel that percentage filled is a better judge of how good a teams' fans are.
So, I averaged where each team ranked over the last five seasons and got my preliminary rankings, then I took into account how good the teams have been over the past five seasons. If a team has been good but attendance has been low, the teams' rank lowers.
After adjusting my rankings accordingly, I looked up TV ratings for each team and adjusted my rankings one final time. So, to the best of my ability, I have ranked all 30 MLB fans.
Note: Attendance Score is the added totals of where each team ranked in attendance over the past five years. The lower the score, the better.
