If the city of Los Angeles is such a hot football market, then why in the hell did the Rams and Raiders move from there in the first place? Another good question nobody has asked or remembered to ask is if the city of LA wanted a team bad enough, then why didn't the NFL put a team in LA back when they last expanded to what is now the Houston Texans?
If the NFL is smart, they would only allow the Rams to move to LA and keep the Raiders and Chargers where they are. The NFL needs Los Angeles a whole lot more than the city needs the NFL. If there were no NFL teams in LA, Los Angeleans have a whole lot of entertainment options to spend their money on. LA sports fans are also more fickle than any woman on the planet.
If Stan Kroenke believes that he is going to show up with the Rams, stink up the joint and the fans will continue to throw down money for tickets, then he is going to be sadly mistaken. They will spend their money on the plethora of entertainment options the city has to offer.
As for the Vikings and Chiefs moving, it isn't going to happen. For one thing, the Vikings will be moving to a new domed stadium next season. If the Wilfs were to move the Vikings at this time, the city of Minneapolis/St. Paul as well as the State of Minnesota would sue them naked.
The Chiefs aren't going anywhere either. Besides the fact that the Hunts are pillars in that community and committed to the city, why would they move the Chiefs? Yes Kansas City is a small market. The Chiefs have a loyal paying fan base and they don't have to compete with hardly anyone for the sport entertainment dollar other than the KC Royals late in their season.
