I'm legitimately curious why you think the modern architecture works here since you already see the flaws in the 70's and 80's style of buildings. I'm not implying your opinion is wrong, I just serious want to know what other people are thinking.
You say it's a stand alone building, but I think it's really not; nor should it be treated as such. Football stadiums are the front porch of every major university. It is one of the most active and visible structures on many campuses. Most college stadiums go into their design process with campus building association as a priority because the stadium itself is on campus. Just because Cajun Field is away from main campus, shouldn't mean we should treat it like it's own thing. It's going to be asked to do the same things, and serve the same purposes as any other college football stadium. That is why I'm emphasizing that the facade matters. Good stadiums add precious iconography to the university. I'd be hard pressed to say a bunch of big blocks of various materials put together to look like a factory adds to that.
I think CF being seen as its own thing was part of its problem and why it's scheduled to be demolished today. It can't survive on its own. It needs the university, because it's for the university, so it should feel like the university. It differs from the soccer complex because like the rest of our athlete structures, none of them will carry as much significance as our CFB stadium.
But yeah, I'm very curious to hear the perspective of people who like the modern exterior.
