How is dumb shit like that not an instant DQ? Zero control of anything, just a gigantic spas with flying bodyweight. It has nothing to do with grappling, if anything that should be considered attemped striking.
Paulo is litterally trying to advance the whole time, but it's not easy getting anything done with Nunes running away the whole time. That said, João is generally more exciting to watch when it comes to no gi as he tends to get more done. João is lot more aggressive and goes for the kill, while Paulo has a more slow and methodical approach.
He was actually the only one trying to attack, Nunes didn't know what to do, he kept doing a back flip and didn't want to face the guard because every time he entered he was attacked. I honestly have nothing to complain about miyao's game on NOGI, I don't like their GI fight.
