A big part me of hates seeing how much gi and no-gi are diverging but I think we've crossed the tipping point. There are only a handful of people left that I think can make the podium at the Mundials and ADCC, and they share a few qualities. I'm sure there's some more, but JT, Lepri, Cobrinha, and Buchecha all come to mind.I agree though, he will never be considered in the same class of the "holy trinity" of Marcelo/Jacare/Roger without dominating outside of no-gi. He's a fantastic specialist, but it seems the sport of submission grappling may have diverged too far for one person to be truly legendarily dominant in both sports at this point.
They are hardened ADCC veterans and deeply understand the rule set. In the gi they have a game that is not that dissimilar from their adcc game (wrestling/not relying mainly on gi grips/crushing top pressure). Another trait they have in common is that most of them have enough mileage to retire sooner than later and not have it to be a surprise. And I guess Cobrinha already did.
Once we see these athletes step away I think the Mundials and ADCC are going to mostly be taken over by those that specialize in each. I think there was one very overlooked element to the lack of success of the no-gi specialists up until about 5 years ago (and it's anything technical.) But this is my 3rd post in a row and I don't want to keep going on and on if the discussion is tapped out.
