No, if anything most MMA fighters can’t even grasp these things. Most don’t set-up any king of takedowns and run to the clinch like Rousey. Most fighters don’t even know hoe to defend. Case and point Khabib running in behind little to no strikes and repeatedly getting away with it. While MMA has come a long way, there are plenty of techniques that have been forgotten or just never realized. Look at the calf kicks that have come to the forefront recently. I’ve seen fighters in obscure promotions use them, and people are just now finding out about it’s effectiveness? MMA coaches severely lacking IMO.
