First, His tiers are off
Tier 1: Ohio State
Tier 2: Michigan, Iowa, Penn State, Wisconsin, Nebraska
Tier 3: Illinois, Michigan State, Minnesota, Purdue, Northwestern
Tier 4: Indiana
Iowa has a better winning % than Penn State in conference play over the last 10 years.
You cannot have 4 teams from tier 3 & 4 in one division. They have to be split 3/3. If you had 4 in one division, that division would instantly become the drastically worse division. If it is all about "competitive balance," they have to be split 3/3.
The same can be said of the top 6. The top 6 must be split 3/3. Arguable, of my top 6 Wisconsin is the worst of the 6 over the last Ten years. But Wisconsin is closer to being 5 than 7. There is a major gap between the 6th and 7th best teams in the Big 10.
The problem with everyone's arguments right now is that they are trying to split PSU, Mich, and Ohio State for the sake of "competitive balance." What these people are failing to recognize is that competitive balance is best in the East/West alignment. The only thing that would have better competitive balance than the East/West would be East/West + Trading Penn State for Wisconsin/Iowa.....but that would make absolutely no sense from a rivalry/geography prospective. Considering Michigan is currently so down, it is very possible that the West will be stronger than the east the first few years.
Delaney said balance was most important followed by rivalries and geography. He did not say balance would be the end all be all. He did not say that they would not make the common sense decisions. Delaney said not all rivalries were created equal. He did not explain whether that meant MN/WI doesn't mean as much as OSU/Mich...or if that meant MN/MI doesn't mean as much as IL/PU. It is all speculation. He did say competitive balance, he did not say name recognition balance. As I have stated in other threads, the population of the east is only 11 million more than the West if you include the entire state of Pennsylvania. The population of the East is shrinking and the West is growing.
In the East/West alignment,
the West had an average finish of 2,4,4,8,9 (5.4)
The East had an average finish of 1,2,6,6,10,11 (6)
So assuming Nebraska is 9th or better, the West would have been stronger than the East last year. 5/6 went to a bowl last year in the west, with 3 wins. 3/6 from the east went to bowls, with 2 winning.
In his North South alignment
The south had an average finish of 1,2,2,6,9,11 (5.2)
The North had an average finish of 4,4,6,8,10 (6.4) + Nebraska
So actually the divisions he has proposed are more unbalanced last season. It also causes the problem of creating a potential rematch in back to back weeks of the same game in the conference title game, because assuming there are locked rivalry games that are played the last week. 5/6 games in the final week of the season would be cross-divisional.
