do usc & ucla share the same football stadium
No, UCLA and USC do not currently share a football stadium. The UCLA Bruins play at the Rose Bowl, located in Pasadena, while the USC Trojans play at the Los Angeles Memorial Coliseum, located in the University Park area of Los Angeles, just outside of the USC campus.
The Coliseum is the largest stadium in the PAC12 with a capacity of 93,607. However, until 1981 UCLA and USC both played at the Coliseum since it was the only viable stadium in the area at the time UCLA started playing football.
UCLA was not ranked in the top 25 at the beginning of the 2012 College Football season, but they broke into the top 25 in all of the major polls. USC is in the top 3 of all of the major football polls. The teams will face-off in the annual big game on November 17, 2012 at the Rose Bowl (time TBA).
