Since they all want to do crossovers, why don't they do fair crossovers, like fighting a boxer under kickboxing rules?
MMA fighters sure got better kicks (though very very far from being perfect for most of them) but they completely lack the speed, coordination, footwork and slickness boxers have.
Would love to know how a Poirier vs Canelo ends up under kickboxing rules. Or Ngannou vs Fury.
