What worries me about Greco is its future. Judging by how the IOC wants each sport to be a 50/50 ratio between men and women at the Olympics and how UWW isn't concerned enough about getting Greco back to being an artistic sport (throws are a thing of beauty), I'm not sure Greco will be around after the 2020 Olympics. My guess is that there will be 10 weight class each for Freestyle and Women's Freestyle after the Tokyo Olympics.
Again, this is my assumption and isn't based off any rumors that I've heard.
