Well, as a SoCal resident, I can tell you that this is the worst fan base for sports. They are the epitome of fair-weather fans. They only care (the majority at least) if you're a contender. It was amazing to me seeing the lack of Lakers fans around the mid 2000s until the Gasol trade and then poof, they were everywhere again. Kings fans are the same. Dodgers fans usually consist of real fans, bandwagon fans, celebrities, and the trash (criminals, gangs) who just want to fight.
Plus, everyone in L.A. seems to be from somewhere else and there are way too many options for things to do compared to a lot of other states that don't have as good of weather or as many options.
Just my thoughts.
