The Mendes Bros have lost matches, it's not like they are invincible. I respect Eddie Bravo and Rener Gracie a lot because on their websites, they post all their live rolls, including when they are exhausted, and even of them getting scored on or tapped. If you train to exhaustion, you get scored on or tapped. I don't care who you are. That might not happen in front of regular AOJ students but rather in closed door sessions, but it 100% does happen.
I don't know who does the video editing and content structure for AOJ, but my guess is it is not the Mendes bros. My assumption is that the person running their business makes those calls, including editing out or just not sharing videos that make the Mendes bros appear anything less than invincible. And we don't know whether or not the Mendes bros are cool with it. All that said, it leaves a bad taste in my mouth all the same.
