Our D will get better (zero pass rush) but our offense has too much for USC. Their LB's are 260 lbs and won't be able to match our speed and diversity. They will be exhausted after 3 qtrs trying to stop our balance attack.
I don't know about the other linebackers but, Brinkley played the game of his life against us last year. USC's offense will struggle because McKinley is most likely not playing.
