I live in CA and travel all over the country watching BYU. From discussions with the local people at those games and on business trips around the country, people know lots about BYU, are excited to play BYU, lots would like to see their team play at BYU.
BYU regularly brings more fans to the games than other teams, even more than some teams in their conference. BYU is regularly on national tv. We suck, but BYU isn't a regional team by any means.
