Forgive me if I'm being Captain Obvious, but this a load of horseshit.
1) he's not the best looking human to have ever existed. Gordon is no Akiyama.
2) maintaining size through sickness is not a matter of how juiced you were or weren't or whether your pre sickness physique was "real" enough. It's a matter of how sick you were and what was happening.
If a guy went from 235 to 165 after nearly dying from covid and spending four months in the ICU his loss of mass really has fuck all to do with his training prior to nearly dying of covid. People dying from cancer, AIDS, or other severe health issues can lose weight like a motherfucker regardless of how "real" their muscles were previously.
If Gordon has something technical to say about sport jiu jitsu I'll listen, I find him to be a much better teacher of John Danaher's system than John himself because he can stay on topic and get to the point.
But outside of his area of expertise, Gordon has habitually proven that he is no more knowledgeable on a wide variety of non jiu jitsu topics than any other high school dropout.
