well since sportjunly posted this i can give you my basic up or downs for these teams. Lindetrain is doing conference breakdowns , so i will wait for his pac 10 thread to give more detailed thoughts...
usc -- finished the year as one of the top four teams in the country , so while i think this team is in fact slightly better , it is hard to be much better than where they finished last year , even if they were to win the title.
ucla - i think this team is considerably worse, though agree that there is great room for improvement and the new staff is more likely to get the most out of its players. 9 returning starters , new systems and injured qb
washington -- yeah they are better. check out their roster as well ... most of this team returns next year and this team makes noise in the pac10 again.... a year away but definitely improved.
ASU -- On paper they look better , but this team got so lucky last year that i dont think they improve at all in wins. The offensive line does not look promising.
arizona - hard to tell , depends on the development of young defense. offense will be solid. they should be about the same though for different reasons than last year.
oregon -- when healthy last year they were an elite team. lose the stud qb and stud rb. Take a small step back this year, but still good. Thought this team was way overrated last preseason and i was wrong.
Cal -- i guess improved. But only because they were so banged up last year ... the talent level a year ago was better.
stnaford - bleh. improved but not by much. usc moneyline
oregon state -- lost every starting dl and linebacker from team that was number 1 vs the rush in the nation last year. ouch. Second best team in the pac10 over the last two combined seasons and now will be lucky to hit 6 wins.
