UW-72,500
UCLA-91,936
USC-93,607
Anyway to start.
#10 Arizona Stadium- University of Arizona
My rivalry based disdain aside, this is usually the unanimous choice. Picture a 57,000 seat highschool stadium. No amenities, very cheap looking. The one distinguishing feature is that 2 dorms and some music classrooms are built into the stadium... though it just means those facilities look as bad as the stadium. They also managed to find the one place in Tucson with no moutain views to put it.
#9 Los Angeles Memorial Coliseum- USC
Historic- yes, big- yes, good atmosphere- eh... still the stadium is a fossil. It lacks many of the basic amenities you'd expect a big-time college football stadium to have; it wasn't built for football so large sections of seats are unusable and about of 1/4 of those that are used have terrible sight lines.
#8 Rose Bowl- UCLA
Ok, let me clarify that this is ranking the Rose Bowl Stadium only as UCLA's stadium. Cathedral of football and symbol of tradition, beautiful views... on January 1st; the rest of the year it is a 1/4 to half-empty stadium depending on how UCLA is doing (and usually there is a large chunk of visiting schools LA area alums and people who want to just see "The Rose Bowl"). Also it is very difficult to get there from West Wood so students especially only show up for really big games.
