I don't know about that. Penn State has looked mediocre these first two weeks. They got spanked by SMU and were taken to 5 sets by High Point yesterday.
Wisconsin is 1-3 right now and has all kinds of health issues. Auguste and Lopez and Egan all are struggling with injuries. They will get better once Decelise Champion arrives later this week, but they are struggling.
Purdue lost their best player for the season with some kind of undisclosed medical condition. Their second best player hurt her ankle and missed a match Saturday. Not sure how long she will be out.
USC looked good against Arizona State, then lost to Creighton. I've never been a fan of USC coach Brad Keller. IMO, no one does less with more than Keller. He recruits great players and they continue to have mediocre teams every year.
Minnesota looks better this year, but they still lost badly to Arizona State. Passing and ball control are big concerns for them, and Swenson is still struggling to find her groove as their setter.
I don't know if Nebraska will go undefeated in the Big Ten again this year, but I will be surprised if they lose more than one match in conference play. There is just no one at Nebraska's level this year.
