Sorry coming late to this discussion, but I've got to chime in here. This is going to be lengthly, so I'll break it up into different posts so you guys don't lose your minds reading. I have to ask what is the purpose of having a class system? Alot of this class system debate has been centered around having a "true" state champion. I'm against a class system, but this is the wrong take to have against a class system in my opinion. I look at it like this and ask, "what does a class system bring that a single-class doesn't?"
The biggest reason I've read, not from this thread, but would be that it brings increased participation. I'm sorry, but I don't buy this because there are more classed-states that are worse than states that are better than Indiana. The states that are better than us have stronger wrestling culture and more people willing to put time into their wrestling product (on top of that, population).
I'm going to be candid in saying that bigger schools do have a built-in advantage with size and funding power, generally speaking. I'm an "anti-class" supporter, but I won't fool myself into believing big schools and small schools are on a level playing field. With that being said, it's not necessarily that big school kids work harder than the smaller school kids. It's the quality of the workouts. Since big schools have the aforementioned built-in advantages, their likely to find more wrestlers.
Assuming everything's equal with the program and coaches. Wrestler A will get more out of a workout wrestling 4 or 5 other kids from Big School; compared to if Wrestler A is working out against 1, maybe 2, at Small School. This is just a general comparison. Now add in the coaching talent, funding, parent participation all should be stronger at big schools. You can start to see the picture of why big schools have more state qualifiers. Again, I'm speaking generally so there are exceptions to the rule. This is my take on this matter.
