They say that it is about having good match-ups, but the real substance is fans not having to go to the same region for multiple years (e.g. Wisconsin to Florida for 6 consecutive years).
This may be good for the fans, but it may give us some bad match-ups.
Translation: I want the right to ***** Iowa, because those hick fans will go to any bowl and nobody else gives a hoot about them. But I can still extort bowls with the promise of their behemoth travelling fanbase.
