Some teams you naturally dislike because they are your arch rivals. There are very few Indiana University or Purdue University fans who root for each other. The same goes for most high school arch rivals.Some teams you dislike because they win all the time. Very few people outside of the New York area root for the Yankees. The same goes true for teams like Alabama who always seem to be in the NCAA football playoffs. In basketball the Duke Blue Devils are not a favorite of many outside of Carolina.I personally do not like the St. Louis Cardinals in baseball because they are in opposition to the two central division teams (Chicago & Cincinnati) that I root for on a regular basis. It seems like until recently it was always the Cardinals on top.Who are the teams you dislike?
