I mean he hasn't competed in 5 years, but on his website against top competitors like Braulio Estima, he actually looks better in some ways than he did when he competed against those people. For example he lost to Braulio twice by sub. Gym rolls don't count but if it's any indication, he's just not in tip top shape right now. But his technique is as sharp as ever.
This is what hype does. I like the Danaher guys a lot and I study them a lot. But in no gi Marcelo is the best ever. 4 ADCC golds ('03, '05, '07, '11) an ADCC Absolute bronze ('03 and '05) and and ADCC Absolute silver ('07). In Marcelo's last year of competition he won the Mundials and ADCC without a point scored against him.
He submitted 24 out of his 27 wins at ADCC and 32 out of his last 37 no gi wins in total. He did all of this with basically just 4 subs. Rear naked chokes, guillotines, north south chokes, straight armbars, and maybe a wrist lock, triangle, and a heel hook. The only two people that he has faced at ADCC and beaten without ever submitting them are Renzo Grazie in 2003 and Leo Santos in 2005. Marcelo did sub only before it was a thing because he only subbed people.
He's only lost one no gi match at his own weight class to Pablo Popovitch (who Marcelo submitted in '05 and 07) by a last second guard pass as time ended, because Marcelo wasn't content riding out a win. Marcelo's only other ADCC losses are in the Absolute, to Mario Cruz ('03) Jacare ('05), Robert Drysdale ('07 Finals), and Braulio Estima ('09). It's worth noting that Marcelo was only subbed in no gi by larger opponents (Jacare and Robert Drysdale).
Not only that but the man innovated stuff that's so simple we take it for granted. I don't even mean the guillotine or the RNC. I just mean the simple seatbelt grip.
The DDS is fantastic and I know they prefer sub only to adcc but I'd really like to see any color of adcc medal among them before we start talking about any of them against Marcelo Garcia.
