Sadly pressure on Purdue and IU won't help. I am currently studying Higher Education and currently on average, when broken down to a microlevel, virtually all division 1 universities are losing $9.5 million each year due to athletics. (Microlevel meaning cost of travel, tutors, coaches salaries, scholarships, legal fees, maintaining athletic facilities, ticket sales representatives, hiring athletic trainers, and so on) Almost every major university in America is hemorrhaging money due to sports. So the pressure most all universities are facing is how to subsidize the cost of sports. Often as a result of trying to save money they cut non revenue generating sports.
Part of the issue is kids in Indiana are conditioned at birth to pick up a basketball. Hoosier lore is true. Indiana hands down is the best basketball state in the United States and is not even close to the most populated. Why? Because of tradition, fantastic coaching, media coverage, the relatively speaking cheap costs to participate, the abundance of youth leagues, the AAU system which promotes traveling to face elite competition, it's classed so more kids have the ability on a "big" stage to showcase their talent, and many more factors.
Indiana wrestling is slowly heading in the right direction. But it is going to take sometime. I think something to consider if the Olympics do not reinstate wrestling the effects could be devastating for the sport and I foresee many universities cutting programs due to the fact their would be no more room for advancement in the sport.
