Since its a man vs. man sport - why are classifications needed at all?

I remember when a little freshman from Sabetha (Matt Pyle) tossed a senior from another 6a town around like a rag-doll before Pyle PINNED him. This senior was good. This senior was a HARD WORKER. I had known this senior since he was a little kid. He finished well. He took third in 6a state that year. Pyle went on to be a state champ as a freshman.

I see no need for classifications other than geography. But, with some creative thinking, I bet that could be overcome.
