I'm sorry but Penn State has and never will be a top 10 team. Ohio State lost to USC, which overall was a good game. The coach has about the easiest schedule, not to mention he only plays to my knowledge 2 legible teams. Ohio State & Michigan.
EDIT:
A good team can lose to a bad team at any given time, it happens. It's part of football. All it takes is to have a few bad plays, other team gets some momentum, and bam, game over. This wasn't directed to the OP by the way. I think California has a better team than USC this year, but that's a big rival so there is a good chance USC may take the win. USC vs Ohio State was another pretty decent rival that has occured over the last few years.
As far as USC losing to Washington, what some people failed to realize is Washington was at home, which they have a very sick crowd, and it can get pretty loud there. They almost beat LSU also, them being at home again. I think they are a better team then what people give them credit for. A team that has nothing to lose and will play harder then a team that has something to lose in my opinion.
