ONE Championship is valiantly trying to change the world of submission grappling as we know it. Not only is the Asian organization giving high-profile jiu-jitsu athletes the pay that they deserve, they are also providing a platform for them to shine in front of the global stage.ONE rightfully gives the same attention and prestige to grapplers as they would their MMA fighters and kickboxers. Simply put, the Singapore-based martial arts organization is trying to make submission grappling mainstream. This is long overdue as grappling bouts can be just as exciting as a slugfest between strikers. View this post on Instagram Instagram PostLegendary jiu-jitsu master and current ONE heavyweight MMA fighter Marcus 'Buchecha' Almeida has spoken highly of ONE's efforts to change the grappling landscape. Speaking to the South China Morning Post, 'Buchecha' had this to say:"That's the best, I think, ONE Championship and [ONE CEO] Chatri [Sityodtong] is doing right now. They are doing a really amazing job with that. It's making the whole world see grapplers like kickboxers, Muay Thai fighters. People that sometimes didn't have the big stage to show their work and ONE Championship is giving them great opportunities."Watch his full interview here:'Buchecha' said it best. ONE is treating grappling specialists like the true prizefighters that they truly are. It's crazy to think that one of the most beloved MMA icons, Royce Gracie, is a jiu-jitsu master. And yet, the sport itself has not achieved the heights MMA has reached. At least not on a mainstream level.It wasn't until ONE made a strong effort to bring it to a global audience that we're actively talking about pure grapplers again. Today, we look at ONE's growing roster of grappling assassins and name three of the most dangerous and entertaining to watch.#3.
