Let the record state that the addition of Nebraska is a fantastic move for the conference formerly known as the Big Ten.
It will elevate the level of play in the conference, makes sense geographically, and will probably spawn a great Nebraska-Iowa rivalry. It will give the Big Ten the right to have a championship game, which they desperately need.
Does it make sense for Nebraska? Probably so, because they were never that great a fit in the Big 12 North anyway.
The only problem is that the Big Ten was always stratified, and now they have become even more so. In this day and age Ohio State, Penn State, and Iowa rule the roost. Michigan has fallen apart with Rich Rodriguez at the helm. Wisconsin is mediocre at best. After that it gets really, really sparse.
Nebraska is a good team that is in the process of improving. They will join Ohio State, Penn State, and Iowa at the top of the conference when they come over. They had better schedule some tough non-conference games as well.
