Michigan is a very good football factory. It isn't a great one.
Wisconsin is also just a good football factory. So are Penn State and Iowa! Ohio State is the Big Ten's only great football factory, and now for the sixth time this millennium it will be formally participating on a national championship stage.
The rest of the Big Ten combined has been here exactly once, with apologies to pre-B1G Nebraska in 2001. So it's Buckeyes 6, Field 1* nearly 20 years into the 21st century. It's not all that competitive, but the B1G is not the current ACC either - we'll get to that in a moment.
