If your particular team makes this list, please do not take offense. Delusional fanbases are often largely caused by a bandwagon effect. Less informed fans swell the ranks and their delusion taints the entire group.
For instance, as a N.Y. Giants fan, I was exposed to an enormous bandwagon effect prior to the Super Bowl. Essentially, they were convinced that the New England Patriots posed no threat at all and it would be an easy win. Consider that the two teams played in the regular season down to the wire and the Patriots were on a 10-game winning streak. I did not see anyway that it was not going to be a close game.
The Giants escape the list because the bandwagon in New York has moved to Madison Square Garden. An ever-present bandwagon exists in the Bronx.
Also, in the Northeast we will visit New England and Philadelphia. Following that, we will be taking our talents to South Beach, say hello to SEC country and pay a visit to the house that Jerry built in Dallas.
We also will check in with a nomadic fanbase, as this player travels often. Finally, we will also check in at the Mile High City.
