Oklahoma State and the rest of the big-12 were exposed by a mediocre at best oregon team last year. a simple look at OSU's record against top-25 teams the past couple years tells you all you need to know.
As for lsu/uw, SEC teams havent' exactly had a good run on the road in the pac-10 (uw is a hard place to play when full too), LSU unquestionably will think they will roll UW, and locker will likely give them some problems until he has his annual season ending injury. also UW massively improved their coaching staff and actually have some decent players.
oh and i'd bet the farm ASU covers the spread against Georgia the next week.
