I agree the best women in the country right now are really good. I agree the training at the top is as elite as it gets and that they function inside of the same elite system as the men.
But I think you are massively underestimating the impact of numbers in a sport. The idea that if Helen Maroulis didn't wrestle we would have just created a different Helen Maroulis from the same opportunities is a strange take. Participation massively matters. The best wrestlers are outliers far more than they are products of the system. Far fewer competitors means far fewer outliers. And outside the USA the numbers are far smaller. If we insist on having GOAT conversations, the fact that JB was best of a far larger field matters. The fact that there are 10 men's weight classes across 150 lbs and 10 women's weight classes across 60 lbs matters. JB has to be the best from 65 KG to 86 KG. Helen has to be the best from 53 KG to 62 KG. If the women spread the weights out to 100 KG and kept 10 weight classes then her job would get much harder. instead of being best from 53-62 she'd have to be best across a far bigger weight range. More of the best women would be funneled into the same weight class. I coached a 190 lb state champion HS girl this year and the UWW says she doesn't exist. Instead they make 10 tiny weight classes for smaller women. Smaller weight ranges and far fewer participants make a big difference. Fewer countries committing resources to the sport make a big difference. If we are going to insist on a GOAT discussion across genders for some reason, these things matter. Just like nobody is bringing up Rex Peery in the NCAA GOAT debate for winning 3 titles in 3 tries for Oklahoma A&M in the 1930s when there were far fewer schools and competitors. Helen Maroulis is incredible but I don't put her accomplishments near the 10 most accomplished US wrestlers. I wouldn't put a men's gymnast with a big medal total near the top of US Gymnasts for the same reason. They get trained in the same infrastructure as the women, but there are far fewer participants.
