I don`t know where you get your info, but, if it was me, I`d get another source. USC has sold out every game, tickets for today`s game are going for well over $1000.
Good article in the slimes sport sec. about LA being a football town. One Sat. in Oct. UCLA and USC both played at home, total attendance was over 170,000
I know that the configuration of the coliseum for USC football games is quite a bit less than maximum capacity.
