http://www.nfl.com/news/story/8313635 I think thats a good idea but I don't really like the game that is going to be played. I don't know any Mexicans that like the Cardinals or the 49ers. All the Mexicans are Cowboys fans.
Ranman is right. Dallas played a preseason game down there and it sold like over 100,000....crazy. I would be curious to know what tickets sell for down there. After the novelty of this wore off, I would wonder if the NFL made more money down there or not. I also wonder which team got paid dearly for giving up one of their home games.
I wouldn't be surprised to see a Mexico City NFL team in the next 30 or 40 years...assuming I live that long.
