Just read this thread in its entirety. For all the reasons listed by pfister, bees, tomcat, orangeDW, orangeXtreme and others, I think this is a terrible idea.
In addition to all the reasons stated for opposing it -- not the least among them being that EVERY SINGLE season ticket holder -- those who have supported the program financially and emotionally for decades -- will probably wind up with a worse seat ...consider the following:
1) Given past experience, we could probably sell 40,000-plus tickets for the current configuration... if the additional tickets were marketed as "obstructed view" or whatever, and you put a huge screen TV behind the bleachers. You could sell a ton more tickets... both in the stands and as standing room.
2) What would you do without the space behind the bleachers? Pre-game, thousands of people (families and kids) wander around back there... buying stuff and playing games. There's also an Orange Club reception area there. It is great ambience, and allows the crowd to arrive over a period of 90 minutes. Where would all these people go if that area is not there? They would have to go immediately to their seats, causing everyone to arrive at the same time.
3) People already complain incessantly about parking. You want to add 7000 more cars?
4) And... suppose there is a blizzard. It is Syracuse in winter, remember? Suppose said blizzard cuts attendance drastically. FSU in the 2007 NIT redux. Now that would be pretty on national TV. Blizzard outside .. and no one inside. After having gone to all the trouble and expense to expand the seating. Fun national story.
As several have said, we are Syracuse. We already have the all-time attendance record -- which we could increase any time we want. Duke, in reality, is just another conference game. And a first-time one, at that. Why do we want to make them special?
