Conor McGregor was knocked out by Dustin Poirier at UFC 257 after a flurry of brutal leg kicks caused McGregor's leg to go dead and weak. Poirier ultimately won by knockout to defeat McGregor, but the leg kicks were really the star of the show to help give Poirier the victory. In this video we'll review the leg kicks and explain the anatomy that makes them so effective in MMA!
EDIT 4:45, these are NOT dermatomes. Dermatomes come from the spinal nerve root levels, these are just the distributions from sensory peripheral nerves.

    Will the UFC 257 performances be enough for Khabib to come out of retirement?? EDIT: 4:45, I mispoke in the moment, these are NOT dermatomes. Those are related to nerve root levels and not peripheral sensory nerves, which is what I am actually showing in the video. Just a difference of describing the cutaneous innervation from the sensory nerve (pictured) or the nerve root (L4, L5, etc) Also, bonus points for those that caught my orange/green background colors

      If it was not the leg it would have been something else b/c McGregor has never developed his abilities..... Professional Prize fighting at the Championship level is about Patience, Thinking under pressure & ADJUSTMENTS....... Of course mastery of fundamentals, technical skills & pure talent are Crucial but at the Highest Levels - Championship Level - these factors are given or the fighter would never be in a Main Event Conor simply does not possess these mental skills & that is why since he has moved to his Real weight class where opponents are the same size & he can no longer bully opposition he has been exposed as a one dimensional fighter who falls apart when his 1st round onslaught fails to work This was very obvious even when Conor was winning early in his career, Conor sets NO traps, there is No clue to his tactics in terms of tricking opponents by baiting them early in order to set something else up later in the fight & this is why Poirier was a perfect opponent to underline how stagnant Conor has been for Years now In short, Conor is the Exact same fighter he was years ago when he was fighting lower level or younger inexperienced foes & he could get away w/ his short cuts Poirier has developed beautifully since then, his footwork is outstanding, he is Always in a strong base w/ feet wide apart & his chin - even when he throws punches - is Safely behind his lead knee - this allows Dustin to always have a backdoor to escape or counter & b/c his technique is so good, even if he does get hit, his chin is not flying forward over that knee multiplying the power of McG's punches Think of baseball when a pitcher is throwing a 100 mph the batter just needs to make contact & the ball explodes off the bat - when your technique is poor & you are throwing power punches & an inexperienced fighter is emotional trying to get that extra on the punch his chin flies out way past his lead knee Conor being an excellent counter puncher always slips that punch or what is called a Pull Counter in Boxing, all your opponents weight flies forward on to his lead leg & his chin is in the kill zone so you merely need to Pull your head back to slip the punch & Counter and his own momentum basically KO's him on your nice, easy counter punch Remember when Conor 1st entered the UFC very few MMA fighters had any Boxing training - the Diaz Bro's were among the very few & they were devastating in stand up b/c of it - so was Conor Most MMA fighters would learn kick boxing fundamentals which are some killer techniques but kickboxing focuses more on Offense, the entire art of Boxing is about Avoiding contact through the use of proper footwork & movement that requires Perfect balance in order to avoid danger, maintain balance while Delivering violence & its one of the hardest things in the world to master Dustin has done a great job of Improving his Defensive abilities in stand up by using basic boxing fundamentals of footwork & even early when Conor was landing, Dustin was more often than not able to dampen the force of McG's power proper fundamentals And b/c Conor's fundamentals are So bad, he was often in a position where he was completely vulnerable to Poirier's counter offense - kicks, punches, take downs..... it was all there for Poirier b/c an increasingly frustrated McGregor began winging w/ jaw right there in the kill zone like a prize, his balance was off making him susceptible to the take down & his momentum from over punching left his body wide open for Dustin to use the calf kick.... Essentially, Poirier just took advantage of what Conor gave him He was patient, made adjustments on the fly & clinical in his total domination of Conor. Conversely, McGregor's only "Adjustment" was to continue to do the wrong things just Faster & we have ALL done this w/ something in out lives..... Its kind of like banging the TV or AC if its not working, or throwing a thing across the room if we get frustrated So while I luv the Doc's breakdown of the calf injury, Dustin would have won this fight in any numver of ways b/c he effectively neutralized Conor's One dimensional Offense..... For example, Dustin was timing Conor's favorite right, jab, straight Left, right hook combo by throwing a check hook from the south paw stance as a Counter punch - Dustin's Own Pull Counter of you will & he was landing it over & over again b/c Conor never adjusted & kept walking right into it, Dustin also used that great footwork to put him in a position to take Conor down after slipped Conor's punches In other words, because Dustin's footwork fundamentals were so good, he was able to slip or dampen Conor's Offense & Still be in a perfectly balanced position while Conor was flailing wildly & off balance & this left Poirier in a position to Choose Any one of several counter Offensive moves - in short, he could just pick off the menu - right hand check hook pull counter, inside calf kick counter, single or double leg take down off the counter In other words it did not matter what happened, Poirier was winning that fight b/c Conor has not developed his craft & Poirier has

      Brian, his leg was dead and now his brain is dead...brain damage. Poirier did not win this fight, he is not better than Mcgregor. Mcgregor lost this fight himself by taking unnecessary hits/damage just to show off his tuffness.

    Almost 1m views. Almost 500k subs. Congrats on your channel, Briain. Ive been here since the beginning. Im happy to see you grow like this. Also, what do you think about these kicks and long term damage to the knee and other structures? Do you think they are too debilitating? Should they be looked at? This is coming from someone who has had 5 knee replacements and revisions. I know pain. It sucks. CTE sucks too, but you only get one set of wheels too.
