“Do Bronx” is a Brazilian jiu-jitsu black belt with 12 submission wins to his name, but finds himself on this list due to the caliber of his submissions. Oliveira is absolutely lethal on the ground, possessing the ability to sink in a submission from any position, and making it look easy. He is one of the best grapplers in the featherweight division and one of the best submission artists in the UFC right now owning multiple wins via anaconda choke, and even a reverse calf slicer submission win.
