Would a giant HD "Godzillatron" sized scoreboard fit with the aesthetics of Michigan Stadium? It would be cool to have the largest stadium with the largest scoreboard. (http://en.wikipedia.org/wiki/List_of_largest_scoreboards_in_NCAA_college...) Have you seen other scoreboards at other venues that would fit the Michigan Stadium look?
Hopefully we NEVER have advertising in the stadium, but what the hell else would they put on a giant screen? Retired numbers? National/Big Ten Championships? Wolverine statue on top? I'd imagine they'd keep the classic MICHIGAN STADIUM lettering on the top.
Also, what happens to the old scoreboards? They are old but they have a certain mystique to them. Maybe just leave them (fully operating) outside the stadium surrounding area?
Just something to speculate about..
