I know we really like to talk about Utah having some kind of issue with fan-support, but they have been filling RES for a long while. And for sure they used every available seat for games against USC, OU, etc.
I understand that attendance can exceed capacity because they count *everybody.* Broadcast, production, the band, halftime people, food vendors, etc.
So I really like that the largest crowd in RES history saw BYU win. But I don't think it means much in the bigger scheme of things.
