It really isn't. I guess the team most people are "offended" by would be Wisconsin. Well, Wisconsin is so far undefeated in what is clearly and obviously the best conference in the country. They already have wins against the teams that are in second, third and fourth in their conference. They have already played 11 games against the top 27 (counting Michigan) in this week's poll, and 8 of them were against the top 15. And they still have games against Nebraska and Penn State left on the schedule.
They might be playing the best of anyone in the country right now.
