It's almost a given that the finals of the next national Madden tournament will be held there (it's been held in Times Square before).
some of the stadium crowd will be watching the screen, you can hardly see the fighters from that distance.
i think most of the people that are going and watching at the top-most sections really know that and are there for the atmosphere of the event. you can see the fight more clearly watching PPV at home but people still wants to go to the event live.
some people are going to find out that they were better off ordering ppv. why would you watch on a big screen, when you can watch for less by purchasing ppv.
as i said, people are in it for the atmosphere of the event and not exactly to watch an accurate event of the fight. why would people want to watch an event with people all around you screaming like crazy when you can watch it at home with commentators and punch stats analysis?
