I miss playing Becky Badger, but I think the divisions have been set up pretty well. I didn't always feel that way.
When Michigan was (very briefly) down, we all wondered why the BoneG felt that it was so important to separate Michigan and Ohio State.
I think we'll see that logic pretty clearly in the next five years. Michigan and tOSU look like they will be very, very strong (just like they have been historically) and that they may often be playing each other for the championship. I think that Iowa's division is tougher right now (with MSU, Nebby, Mich, and NW), but I think this evens a bit if PSU can progress. OSU and Wisky will of course be strong. Purdon't is a question mark moving forward. Illinois has to resurrect itself...again.
If Michigan and fOSU are both recruiting nationally at a top-5 level (as they did this year), and everyone else in the BoneG is around 40th, I can see Mich and fOSU playing each other in the championship game a lot.
