I think there are a few factors involved:
1. Population density is greater in most of those states. More athletes to go around and a greater chance that lightening will strike and you will more well wired athletes on the mat. Hard work will take a person so far and then a certain amount of genetics comes into play.
2. Quality of coaching. We have good dedicated coaches in Indiana, but how many of them have competed at the college level for any length of time? Most of the states listed have alot more colleges that offer wrestling than Indiana does thus more potentially better coaches. Does it mean that a wrestler who has competed in college for four years will always be a better coach than someone who is a "Lay" coach....absolutely not, but if you had a poll of ten and the only thing you knew was the level of competition that they had attained to then which ones are yo going to bet on as far as being the best coaches?
3. Tradition. In Indiana we continue to struggle with tradition. We have our tradition the only problem is that it is limited to a relatively small circle of people. Basketball is so huge in Indiana because of tradition. Football has made great strides and has went from only a few kids being looked at by Major Colleges to where it is more common place. The Colts have helped Football. I think that ISWA programs have helped wrestling move from almost no National recognition to the point today where we are thinking about how can we get into the elite group instead of simply how can we get off the mat which was how it was 20-30 years ago.
Solutions:
1. There is nothing we can do to make our population as big as PA, NJ, CA so why worry.
2. Our coaching has improved of late because of efforts by the ISWA and the IHSWCA, but we still have a ways to go. We need to continue to get more coaches involved. We need to strive to develop college programs. Louisville has been talking about wrestling. It is in Kentucky, but that would benefit Indiana wrestling in terms of post HS opportunities as well as them graduating people that might want to coach. We also need to figure out ways to encoourage wrestling at Indiana colleges whehter it being adding the sport to their actual programs or developing teams that will compete at the NCWA level.
3. Our tradition has improved due to the various wrestling organizations and we need to keep working to showcase the benefits of kids wrestling. We have to continually inspect our image to see what we can do to make our sport look good. Sometimes we shoot ourselves in the foot.
Enough for now.
