I completely disagree with your statement and your overall argument. You think the main reason that Indiana is not as good as Pennsylvania is they have class wrestling? By that crazy logic we would never be as good as Pennsylvania anyways because our Population is 6 million to their 12 million. When you throw in a state like Iowa which only has 3 million it makes the argument look even more ridiculous.
When no other factors are involved you will statistically have more talented wrestlers from a big school. When you add in all the factors that actually matter like coaching, culture, and wrestling knowledge that is when you see differences. Look at Indianapolis North Central (No offense to any who goes or went there). They are one of the largest schools in the state. How many wrestlers have they had at state in the past 10 years?
You guys think there is a quick easy answer to solving the problem as why people are better than us. I will tell you that the same thing that made wrestling great in every other state is coaches that put time in with wrestlers, getting lots of young kids to come out and stick with it, building a wrestling culture, and hard work.
