Browse all of the posts in all of the threads. You're misunderstanding probably results from giving PSU, OSU and Michigan too much credit for their performance over the last 15-17 years and giving Nebraska, Iowa and Wisconsin entirely not enough.
You're missing the point, the credit I give to Mich and OSU is meaningless. What matters is that THEY will give THEMSELVES too much credit.
My question was why would they support being in the same division, and I stick to the claim that I believe THEY would fight it. And as the most successful teams in the Conference (currently), they will likely have considerable clout. I presume that at some point, everyone will be in a room debating the alignment.
Here's the argument that Mich, OSU, WON'T make:
"our success over the past 15-20 is overstated. In reality, we aren't that much different than any other team and thus putting us in the same division is fine."
Here's the argument that Mich, OSU, WILL make:
"our programs are clearly stronger as the past 20 years have demonstrated. Balanced divisions are in the best interest of the Big Ten, so we should NOT be in the same division.
what's more, the Mich-OSU game is one of the MOST WATCHED games in College Football. With a dedicated rivalry game, the Big Ten could have this game TWICE A YEAR if we are in separate divisions. Think of the audience if the Big Ten championship is viewed as a Mich-OSU re-match!"
...their selfish reasons will be because they won't want to have to beat each other to get to the Championship. But the above is how they will argue. Rightly or wrongly. I hope it goes geographic, but if they argue in their own best interests, they will fight to be in separate divisions.
