Yeah 65 is an actual mess in terms of predicting who is going to win it every year. I think it also has do to with the fact that the vast majority of countries can field top level guys at that weight class. Compare that to 57 or 125 where the number of elite guys is far less purely due to genetics. It is very unlikely you will find an elite 125 from Japan or an elite 57 from Iran because of that. I also think there is a lot of parity because its pretty much impossible to prep for 8-10 high level guys for a worlds/olympics. Olympics last year had Muszukaev, Dudaev, Amouzad, Retherford, Kiyooka, Rivera, Aliyev, Ochir, Akmataliev and Tevanyan. More than half of the guys in the bracket were world/olympic medalists. That's just stupid depth. So a little under performance in one match can cost you a medal. I think this is where the Russian guys benefit the most because of how nuts their brackets are domestically they are used to it so they better navigate through. Whereas in Iran and US there isn't as much depth domestically so our guys aren't as used to these sort of brackets.
