well i guess i should chime in here since i'm one of two San Antonians on this board...
i hope they get a chance to play here - the Alamodome is a nice facility that the Spurs used to play at until SBC built the SBC center which is nicer, bigger, and has more capacity. The Alamdodome is kind of small for a NFL football field stadium, but will get the job done.
There is NO chance whatsoever that the team relocates here permanently. I do not see that happening - too much politics behind that.
Besides, the "indigenous" people here aren't much for NFL fans.... the Spurs are the thing down here, and every other car has a damn spurs sticker on its back window. They love their Spurs down here.
I personally don't care for them. But it would be nice to be able to watch a Dolphins game in person for the first time in ten years. I know if they do come, myself and Yardman13 will be at the game with Jerseys on... Just look for probably the ONLY aqua and white jerseys in the house
