The more I think about this the more I come around to the idea that the CBI doesn't make sense for Iowa.
Yes, I would love to see Iowa play more. But they've already played 32 games. That should really be plenty, and they've had ample opportunity to earn the right to play more. How many times did Iowa come into a game with a chance to really firm things up-- either to play their way into the tourney bubble, secure themselves a .500 record in the Big Ten, or at the very least lock up an NIT bid? There were tons of opportunities that they did not take advantage of, and they didn't exactly fall victim to other teams playing out of their minds.
Think of it this way-- what does it say about a post-season "invitational" tournament when you have to pay for a spot? It reminds me of those "all-star" camps in youth basketball where kids are "selected" to be an all-star as long as they pay the $300 registration fee. I know people are comparing it to lower-tier football bowls, but that's exactly my point. Why take the aspect of Division I football that everybody hates and import it to basketball?
There are 100 teams combined in the NCAA and the NIT. There will likely be at least nine teams out of the Big Ten selected for those tournaments. If Iowa can't earn their way into that group I don't really see how they "deserve" to play more.
