What makes us dislike teams?

Sometimes the reason that we root vigorously against a particular team is just instinctive, but other times it is easier to pinpoint. It may be a traditional rivalry (Little Rock  vs. stAte). It may be because the team has an obnoxious player (or player's parent, see UCLA). It may be because of prolonged success (NY Yankees). Or because some relative of yours is from there and you merely want to perpetuate a friendly rivalry. It may be because the coach is a scumbag (West Virginia, Kentucky, Louisville). It may be because of some memorable, bench-clearing fracas or off-court confrontation in years past (see New Orleans). Or, as we said above, it may not be a definable reason, just a gut instinct.
