Roy, I wouldn't call the Big 12 stronger then the Big Ten. It just isn't really as a whole. The top team ala Texas or Oklahoma is probably better then the top team in the Big Ten, year in or year out (though Ohio State has held its own against Texas and destroyed Big 12 champ Kansas State), but from top to bottom I'd take the Big Ten any day of the week.
And it definately appears that Missouri and Nebraska will be leaving the Big 12 for the Big Ten any day. It will be interesting to see who else the Big Ten has called on and how big they want to go. I just can't see them adding two western teams and Notre Dame without making a play for the east at all. I'm guessing the Big Ten goes to 16 by adding Nebraska, Missouri, Notre Dame, Rutgers, and Connecticut, shunning Pittsburgh and Syracuse.
You also might see 4, four team divisions.
1
Ohio State
Michigan
Michigan State
Northwestern
2
Penn State
Rutgers
Connecticut
Minnesota
3
Nebraska
Iowa
Illinois
Missouri
4
Notre Dame
Wisconsin
Purdue
Indiana
Each team would have a protected rival and a semi-protected rival from another division. Each year you would obviously play your division, another full division, and your protected or semi-protected rival. The two divisions that played each other would be matched up for conference championships purposes.
A sample schedule, using Ohio State would like this
Year 1 - Michigan, Michigan State, Northwestern, Penn State, Rutgers, Connecticut, Minnesota, and semi-protected Purdue
Year 2 - same but reverse home and away
Year 3 - Michigan, Michigan State, Northwestern, Notre Dame, Wisconsin, Purdue, Indiana, and protected Penn State
Year 4 - same but reverse home and away
Year 5 - Michigan, Michigan State, Northwestern, Nebraska, Iowa, Illinois, Missouri, and protected Penn State
Year 6 - same but reverse home and away
You then repeat the process
Protected Rivals under this format (obviously open for discussion)
Ohio State - Penn State
Michigan - Minnesota
Michigan State - Notre Dame
Northwestern - Illinois
Wisconsin - Iowa
Rutgers - Missouri
Connecticut - Indiana
Purdue - Nebraska
Semi-Protected Rivals (also obviously open for discussion)
Ohio State - Purdue
Michigan - Notre Dame
Michigan State - Penn State
Northwestern - Missouri
Minnesota - Wisconsin
Rugers - Indiana
Connecticut - Nebraska
Iowa - Illinois
