My thoughts are probably similar to many others.
I don't have any problem with a b******* in theory. If I felt confident that 80 percent of the stadium would be in black, then I'd be all for it. The problem is that too many people won't get the memo. Not all, but many fans are in their 60s or 70s and don't use social media or post on message boards.
To get something like this to work, meaning the whole stadium as opposed to just the student section, it needs to be planned out months ahead of time. The university has to be involved and sending notes to season ticket holders that the game will be a b*******. They also need people at the doors of the stadium giving out free black shirts to the people that are wearing different colors. Or maybe they just need 90,000 black shirts placed on every seat in the whole stadium.
