UNDATED (AP) - This is one of those rare weeks when even Michigan hopes for an Ohio State victory. Minnesota wouldn't mind a win by Wisconsin, either. There are four games this Saturday pitting Big Ten teams against top Pac-12 competition. This is the best opportunity until bowl season for the conferences to establish themselves as powers of the sport. No. 4 Ohio State plays at California. No. 20 Wisconsin travels to Arizona State. No. 23 Nebraska hosts No. 16 UCLA. Illinois takes on 19th-ranked Washington in Chicago. No. 17 Northwestern got the Big Ten off to a solid start by winning at California. Like Michigan coach Brady Hoke, whose Wolverines took down Notre Dame last week, Wildcats coach Fitzgerald says he'll be rooting for the rest of the Big Ten this weekend.
