I think Occam's Razor works here, and I think the simplest explanation is that we have a reputation as a team that doesn't draw fouls and that gets into the refs heads. Biases of this sort are perfectly normal and should be expected. I don't think there's any evidence of a conspiracy at all. This league has bent over backwards to make us feel at home, unlike PSU when they joined.
I don't like the officiating in the conference, but it's not because the get together to find ways to job Nebraska. They do appear inconsistent, especially between halves of games, and I'm wondering if they don't huddle up during halftime and critique themselves and then call the game differently based on that critique. That's almost what it looks like.
We lost last night because in that critical stretch we couldn't knock down a shot going inside; getting blocked or stripped and MSU hit every shot in response. Next thing you know, one point game was an eleven point game. That's how these things go.
