Let's see now...3rd place in one of the divisions of the 4th or 5th best BCS conference.
So far leaving the Big 12 hasn't turned out too "Rosy.". 18 months ago, we were in our second straight championship game of the country's 2nd best conference.
According to the pundits, we descended to mediocrity after all. I sure hope they are wrong, but so far the evidence suggests they are spot on. See last year's Northwestern game (yes, they beat NU in Lincoln. Yes NORTHWESTERN) as case in point.
Did you ever think that the two conferences are different and that the team didn't suddenly take a dive?
Try switching jobs every week for three months and see how well you come out of it at the end.
