Vieira shared his thoughts in a recent episode of the Trocação Franca podcast:
I think it’s hard to say who’s the greatest, but I think it’s between [Gordon] and Roger. But really, with the age [Gordon] has – if you look at Roger when he won the ADCC 2005, he didn’t have the age [Gordon] has.
He still has so much time ahead, and he’s already showing a super high-level Jiu-Jitsu, so mature.
He fights beautiful, very aggressive, to submit, and I love watching him fight.
And, even though he rooted for Andre Galvao to win this year’s ADCC superfight, Vieira understood why Gordon Ryan is so dominant:
He made it look easy at this year’s ADCC. I was rooting for Andre, of course.
Deep in there I knew Andre had a chance, even though many people said he didn’t, that [Gordon] would catch him, but I really thought Andre could win.
Unfortunately, he didn’t. He was able to neutralize Andre’s game and did what he did.
And the fact he had a 40-minute match with Andre Galvao and still asked to compete in his weight class… You can count on the fingers which athletes would have the guts to do that.
So, who is going to be considered as the GOAT in the end? Vieira thinks he has an answer:
It’s hard, it’s between Roger and him… But I believe one more [ADCC] win and I think he will be considered [the GOAT], no doubt.
