I just don't get the NFL's obsession with LA. They've lost two teams already. I know it's big market, but the Rams never had a huge loyal following, and the Raiders brought with them an already loyal fan base. They will NEVER build a loyal fan base in LA fro the ground up. Like already mentioned, there is so much to do already in the area, and so many liberal artsy, hip, trendy, Hollywood star wanna-be's...if you're not already a fan, you won't suddenly become one. You'll have you're typical fair-weather fan and bandwagon jumpers. When the Steelers played the Rams in the SB, there was this certain glitzy, Hollywood appeal to it, but the Rams quickly faded back into obscurity once they lost their key players from that team.
My guess is the NFL wants to get that Hollywood face-time. Just like Jack Nicholson was a regular at Laker's games, the NFL wants those camera captures of the trendy star a'la mode.
