Richard:

My guess is that she is talking more about height and muscular structure. I know last year my son was wrestling at the top of the 10 & under age bracket at 120. He only weighed 115 and had some decent height and muscle to him. He faced a couple of 8 year old boys who were coming up an age bracket for the competition. They were shorter and not as lean or muscular. My son pinned them fairly quickly in the first period and I thought it did not help those 8 year olds at all to experience that. I think it is more likely for a young heavy kid to experience these imbalances in height and strength against a boy two years or more older. But I also am not in favor of 6 and under at State for reasons that you and others have stated.
