There are some Rams fans here. However, you are right to ask. Southern California is so heavily populated, with most of that being from somewhere else that those people who have moved here still remain loyal to the teams that represent where they moved from. Like me. Been out here 30 years but still love the Saints. You have a very fragmented NFL fanbase here. You will see a lot of Bear fans. Packers as well. I would venture to say the Raider fans are a plurality. Then you got the Cowboys with a big following too. Just today, I saw someone with an Indianapolis Colts license plate.
