Maybe it's hard to tell. Obviously we add a few very good teams but in what shape will they be in? Like 3 of the 4 lose their QB after this year UCLA seems very weak. Assuming Michigan and tOSU remain stable. I think Purdue, Minnesota (assuming fleck leaves), Iowa (assuming their coach leaves). Wisconsin I do not believe in him as of yet and they are really struggling, Michigan st I think struggles. I think northwestern will ultimately struggle though they are doing ok right now. Indiana is going to struggle as well. Maryland I think crumbles after QB leaves.
Heck if Nebraska can figure themselves out Penn State ain't a world beater. But again that assumes Nebraska can actually get right.
