The 30th team on the list above is at 56,000 range. So Oregon and below meet the standard you suggest.Yeah, but most Pac 12 stadiums just aren't that big. Even if every program sold out every game, most wouldn't crack the top 30 on this list
|USC||Los Angeles Memorial Coliseum||77,500|
|California||California Memorial Stadium||62,467|
|Arizona State||Sun Devil Stadium||56,232|
|Oregon State||Reser Stadium||43,363|
|Washington State||Martin Stadium||32,740|
The point about why the Pac 12 lacks behind in revenue has partly to do with attendance as a barometer of enthusiasm.
