I know Smashmouth has a point and others about a new facility.

N.O. and the state has had so many wrong, half-ass things, but the Superdome was one the really good things. The SD still looks good. Now, I have not been to other NFL stadiums, so yeah, I don't know what the rest look like. I will assume the SD is still one of the better sports/concerts places.

By the time a SD is built, price could be about 2 billion-imploding old one, building new one, time away for team to play some where else.

Yeah, where else could a new SD be built but where the old one is.
SD has the Hornets/concert N.O. Arena. These two places together really are a good thing.

Bienville, ghetto land on the outer edge of the Quarters, is dangerous.
SD is safe to walk around because it has a busy main streets, Poydras , there. Harrahs is right up the street.
The down ramp coming from Met. is alright to drive down and the ramp going up to go to Met and that way is right there.
N.O. Shopping Center , which was really a booming shopping center, downtown for tourists and locals, office place, etc. a little before Kartina. It will come back.

Algiers, I personally would hate the new Orleans Saints to be at any address other than New Orleans, LA.
Algiers is not around any tourists destinations. Traffic on the bridge is the only way in/out and it is tight on a regular weekday.
Other NFL teams like NY Giants ,Jets don't really belong to NY. I never got with that. Why not officially change the name to NewJersey Giants, New Jersey Jets?
There are many points from both sides, but I like SD as it is, where it is.
