No way Kansas is on the outside looking in. They are 50 miles from a major market and have one of the best basketball programs in the country. They are also a member of the Association of the American Universities (AAU) which is a big deal to the Big10. TX, TX A&M, Iowa State, Nebraska, Rutgers, Colorado and Missouri are also members.
Because of this affiliation I can see it very likely that all or most of these schools get added to the Big10.
Of those listed TX A&M, Iowa State, Colorado and Rutgers are the only 'questionable' schools due to limited athletic success. Rutgers adds a HUGE market in New York, TX A&M will almost certainly be a package deal with TX and Colorado adds another huge market in Denver. Iowa St should panic as they don't bring a major market or athletic success.
Assuming we add 5 of those 8 schools, the Big10 would have 16 members which is the right size. The theme here is that Iowa State should be worried.
Every member of the Big10 is a member of the AAU.
