Isn't San Antonio going to be taking in more of the New Orleans residents? If they are and they're staying in the Alamodome, doesn't that take San Antonio out of it?
In all honesty, and I only base this on my own opinion from what I've drawn from the broadcasts of news people who are IN New Orleans who say the city may be uninhabitable for many years, I'd be inclined to think Los Angeles will be the permanent destination for the Saints within about a year. It gives the NFL their # 2 market back which has been rumored to be the destination of so many teams the last ten years and allows the Saints franchise to kind of start over in the short term rather than have to wait out a rebuilding of New Orleans.
