Maia destroyed Magny with slow but constant pressure passing. I remember Magny having a decent guard in some of his previous fights but Maia made him look like a complete white belt on the ground.
I would love to see a breakdown of Maia's passing. It almost looks like he's stuck in mud, yet his opponents simply let him pass to side control then mount or straight to mount. There is something he is doing with his weight distribution, positioning, or timing that should be studied.
Also the gable grip choke he did on the UNDERHOOK side was a thing of beauty.
