This is my thought exactly. In a normalized world, I think over the course of a decade, each of Iowa, Wisconsin and Nebraska should probably win the West an average of 3 times, with each making maybe 2, 3 or 4 appearances in the title game (no one's dominant over a long period). Then, add in one fluke year where one of the other 4 teams wins it. Heck, if things really normalized, we'd see Illinois and Purdue become respectable again and the distribution would basically be 5 teams going twice a decade, but I just don't see that happening. And I toss out Minnesota because they have sucked for so long and have proven to have a lower ceiling than either Purdue and Illinois. Of course, I like Northwestern, but I think their title appearances will be limited to maybe once every 25 years or so unless Nebraska stays terrible and Iowa and Wisconsin totally crap the bed.
We really need to either equalize or get an edge on Wisconsin because Nebraska will at least get back to Pelini levels at some point and that will be plenty to contend for the West every 3 years or so.
