People forget that College Gameday is something that's put together with entertainment in mind.
I am willing to bet that commentators have been stuck pushing a position that they really don't believe in so that the show can be either balanced up one way or another, or skewed to favor one side or another based on what was discussed in the production meetings.
There is also the "character" element, where they intentionally put people on to be the on set "homer" for whatever team or conference. And they have Lee pick teams so that they can have a big moment at the end of the show. I bet, on average, he picks the home team more than the visitors at a live set... just my guess there.
In the end, the show's goals are probably to entertain first and to attract eye balls to ESPN.
And I think that is why we Husker fans feel slighted by the show. Yes, we love this team. Yes, there are a lot of Husker fans out there. But when it comes to population and pleasing the masses....the east coast, deep south and west coast are where the bread gets buttered. Fair no. But most definitely true.
