Douchebag millenial aside he is truly one of the more dangerous BJJ fighters out. (Not to be confused with the best. He is nowhere near the best skill-wise, but he is aggressive combined with his slick and accurate leg locks make him dangerous.)
Seriously, the ability to leg lock like that is akin to one punch KO power. The fight can end at any moment. Just wish it was Tonon getting this attention and not Danis.
