Its a good idea but only because college sports in general has totally lost its mind. The Big XII is correct in doing something to keep up because it is staring irrelevance in the face with its limited footprint, mediocre results, less teams, lack of title game and playoff appearances/wins in relation to its peers.
That doesnt mean that the clearly obvious cash grab title games or ridiculously inflated superconferences or obvious shilling from networks that have TV deals in place with certain conferences are good for the sport. It just means that the Big XII needs to stop pushing against the grade if they have any ambition of long term stability. We can debate all day about what should and shouldnt be, but the reality is for the Big XII is that this is the way they must go to keep up, and they should still look into adding members outside of its traditional footprint sooner rather than later.
