Do you think a boxing match can sell out a stadium? So far the only one that comes to mind who was able to do so is Julio Cesar Chavez when he faced Greg Haugen in the massive Estadio Azteca (around 120,000?) in Mexico. When I have seen a fight in MGM Grand, even on the last sections it looks ooookay, imagine a stadium, not so sure. If it sells out, the fight itself, crowd roar, ambience, etc. would be worth my trip to Dallas. If I could choose, I would rather have it at MGM Grand.
