He is. But in fairness, I don't think anybody really had "No gi GOAT" as a goal until about 4 years ago. All the top guys he competes against were & are doing both the highest level gi and no gi tournaments. I would guess that his competitors are training without the gi about 15-20% of their time at best. In an ADCC year, they probably start training exclusively no gi around June after all the major gi comps are over. It's obvious they're going to be at a significant disadvantage going against him in no gi in the same way they would have a ridiculous advantage against him in a gi match.
It's not to diminish Gordon because he's as legit as they come and he has a really clean, dominant game. I am just recognizing that there is a shift and a split between Brazilian Jiujitsu and Submission Grappling. It's as different as Judo is from Greco. Neither is better than the other and there is a lot of crossover skills, but it's just different.
Exactly. The whole idea of a pro no-gi-only circuit is a relatively recent thing.
It's amazing how fast people forget history and think the way it is now is the way it always was.
