compared to city and university size for most of the rest of the Big 12.

Sports teams in general are downsizing stadiums - just look at the Marriott Center going down from 21k down to 18k.

Sports obsession/fandom is decreasing around the country with the younger generation. People nowadays will more often choose watching the game on tv instead of sitting in the nosebleeds.

I bet the business plan for the new Baylor stadium was to increase prices everywhere. Then they try to sell out every game instead of just selling out a few games a season. It is a risk, because selling cheap seats in the nosebleeds is a way to nurture the fandom of rising generation and the non-wealthy.
