LA won't get any team anytime soon. Two franchises have left already. There is too much to day on a Sunday too go see a bad football team. Literally you have choices of skiing in the mountains, swimming in the ocean or off roading in the desert and every other summer sport you can think of year round. That's why LA fans are so called lethargic. Their not lethargic, their having fun somewhere else.
San Diego is more hard core for supporting their team, which bucks the trend.
Toronto is probably a good choice, but what other big US cities could support a team that currently doesn't have one ?
