I used the 4 years because that's when they still had their B12 roster and coaching staff. It was their first 4 years in the B1G.And you think comparing 4 years of data for Nebraska to 21 years of data for Iowa was a good way to make your point?
You could have just used the same 4 year time period for Iowa (2011-2014) and made your point even more convincing since Iowa went 15-17 in B1G games during that time period.
This is very difficult for you to comprehend, so just move it along then.
