First of all, he's not just a "BJJ guy". He's actually more well known for what he did at ADCC than the Worlds/Mundials and many of their competitors aren't even pure BJJ/Jiu-Jitsu players, they're submission grapplers. Second, in the context of MMA he's absolutely not a great grappler. He doesn't even make Tapology's greatest grapplers of all time in MMA list. There are over 120 fighters on that list yet Monson isn't on there.
He's one of the most
decorated submission grapplers to ever compete in MMA is what you meant to say. So, are you going to tell me about "K-1 level" strikers next and how they're technically superior in MMA as well? LOL. That was a hard lesson some of you guys learned and yet you continue to conflate pure grappling/striking sport credentials with actual ability in MMA.
