I agree with his retiring having a major impact on Wisconsin. However, I'm not sure I follow the logic in having a major impact on the B1G. I realize he threw his weight around bending things in Wisconsin's favor with the B1G brass, but at the end of the day it probably didn't have much of an impact on most of the B1G especially the Ohio State's and such.
Scheduling influence being the biggest pain in the a$$. he was the head person of scheduling for football within the conference and always made sure they didn't have as tough of a schedule as other Big Ten West teams and would always make sure Nebraska had a tough schedule. Who do you think pitted Nebraska against Ohio State right off the bat? lol.
Besides the change over the course of time for offensive philosophy for WI (and it will happen), is the scheduling aspect of things.
