Kushagov is a true sportsman. He knew Marcos was out of it, and didn't jump on him and throw unnecessary strikes. And then once the fight is called, he even steps in to help the referee steady him. No running around the cage and acting like an ass. Need to see more like him.
Any delayed concussion is worrying. It can be a sign of brain bleeding. Because if the bouncing brain wasn't enough to bring you down, the pressure of blood pouring into your skull cavity will.
That head movement that guy on number 2 uses on big John after the inverse triangle choke is something to behold, I bet his coaches were proud that he really internalized the head movement and ground and pound defense drills 😆
"And if you find yourself alone, riding in the green fields with the sun on your face, do not be troubled. Keep your eyes on the target and them head movements going" Wow what a gladiator!
Sorry but that ref at 3:19 should reconsider his decision to be a ref. The man was waiving the opponent off, staggering, and his face did not show he was aware and at that point the fight should have stopped and the opponent should not have been able to throw 8 or 9 more punches.
The ref only?? The fighter too! There are humans doing sport fights: those STOP when the enemy is hurt. And there are sadistic psychopaths who gleefully beat and opponent into the wheelchair or grave when he is defenseless... As a punishment, I would give the victory to the guy on the ground, when the ONLY purpose of the continued attack is to do harm AFTER the victory was already achieved.
@@meleardil Sadistic psychopaths... MMA is probably not the right sport for you and you should watch tennis. Fighter have often a tunnel vision meaning they blend everything out except to physically hurt the opponent until the ref stops the fight. Blame the fkn ref.

I had one “standing ko”, and it’s fkn scary. I was sparring with my teammate and next thing I can remember is being at the corner, hands up, and my coach saying “Son, you are OK, let it settle and breath”. I (apparently) was solid 10 seconds standing, eyes rolled and tense as a rock. Two days at the hospital, so this ain’t funny at all for me..
@@Philthy82 Absolutely. The sad thing is when you are defeated in a ring you always learn something. In this particular occasion I learnt shit, because I can’t even remember being hit 😅
@@joanmarinos4828 ha ha! No replay either! I've been KO'd before, came to on the way to the hospital. Bizarre experience, unfortunately, I was KO'd playing hockey. Not as epic as a fight! 😂
@@Philthy82 LOL! But it wasn’t a “real” fight, just sparring! OK, we both were heavyweights, but we were wearing gloves and helmets and was more about technique than hurting the guy in front of you. Imagine this guys, Pros, with MMA gloves and full power! Just thinking that, I literally would sht myself after the bell if I must face any of them 😅😅😅
7:18 dude had a rock Lee moment...but jokes aside that's crazy, imagine training so hard and religiously and having so much determination that even once your conscious mind has ceased to function your body still refuses to give in and starts to act on its own.
I think #11 scenario is that person who got 'knocked out' had a cardiac arrythmia vs. a vasovagal like reaction due to pain AND anxiety secondary to pain. Interesting video. Thanks for posting.
It can happen if you just stand up too quickly period. Doesn’t require you having been asleep. I routinely lose vision while standing up too fast, so it’s a matter of degrees. I’ve never fainted, but I can feel in often in the urge if fainting, or at least losing a sense of equilibrium. So I usually grab a wall and ride it out.
For your future videos it would be nice to see more of the fighting clips. Just my personal opinion, but I like seeing the clip first to get a natural reaction, and then hearing the commentary explain what I just watched,
Blame the refs then because as you saw with omalley vs Almeida sometimes you think an opponent is out but the ref actually let's it keep going. The fighters job is to fight until the ref stops it.
It's a bad ref thing. If you severely daze your opponent and stop, the ref might allow the fight to continue and because you didn't press the advantage your opponent might recover. This is one of the worst things that can happen in a fight. It's not good for you, who might lose now because all it takes is one well placed punch for the fight to turn, and its not good for your opponent because they may end up taking more damage than is strictly necessary. Really the best thing for both fighters is to continue to attack until the ref stops the fight, and hope that the ref is good enough to know when to call it.
@@Amehdion Yeah, there have been fights people thought they won and then lost. But some KO's are obvious. Hendo didn't need to punch Bisping on the ground that hard. Mark Hunt looks like a boss with the walkaway KO's, same with O'Malley. That is a good trait, I think. They don't care if the fight goes longer -- a chance to win twice. That's a good attitude too.
What happened with the Luke guy was his brain literally on the verge of death. I saw a very similar reaction after pulling a man from the waves at a beach once, he hit his head on the sand body surfing and got knocked out and was drowning. I don't know the medical reasoning, but I assume it has something to do with the Autonomic nerve system, like when we shiver to generate warmth, the movement was his muscles trying to squeeze blood to make it move to the brain.
Yoooo Mr.Westfall is my fav substitute teacher. He told our class that he was in a 2.5 million view RUclips video and told us to search us "most unusual knockouts". This is pretty cool!
Most unusual knockout for me was when a fighter knocked his opponent down but when he dropped to finish the job his opponent raised his knee without thinking. He hit the knee knocking himself out
I love this list. Have you done a "How sis they stay standing" list? Like Hooker vs Barboze or Holloway vs Ortega and equally impressive beatings from other organizations.
The first KO at 1:31 shows the peak performance of this ref. Every ref that doesnt jump onto the falling guy immediately and ways off the fight instanly needs a serious debriefing
The ref hadn't stopped the fight. Like what the fuck are you talking about? The fight goes until the ref stops you. This isn't kids kicking balls into nets this is grown men slugging it out.
@@jasonjackson5696 Does that change what I said at all in any capacity? You want the alternative? Okay then you end up as the guy who walks away before the fight is done and gets his ass knocked out.
I get that the goal of an MMA fight is to hurt the fighter to win. But can we all agree that hitting the other fighter when they aren't right in the head is uncalled for?
Man when that guy was waving off like that and kept taking blows ... and the ref just stood there watching... I would hope he lost his job but probably nothing happened. Thats like if youre in a choke and tap out but the ref just stands there watching you as you descend into unconsciousness.
One of them that, to me, was kind of insane was Rampage vs. Lidell 2 in the UFC. Rampage cold cocked Lidell and Lidell went rigid. A few seconds later, after the ref checked on him and teams were entering the cage he looked around like "why the hell are people in here? I have a fight." Like he went ktfo to alert real quick.
That Burgos one was just like when you click “shut down” but your pc has to do a couple quick updates and then shuts down. He woke up with up to date firmware and the newest drivers but for some reason his chrome shortcut wasn’t on his desktop anymore. 🤷🏼♂️
The guy at #8 who waved his hands right at the other fighter saying he's done. The guy keeps hitting him 4-5 times 3 after the guy was knocked out. No self restraint or common sense. The fighter waved him off. The ref omfg how stupid.The same with #1
it’s not morally right but you gotta understand that once you’re in that ring u fight to kill and you fight until the ref says otherwise the only ppl at blame are the refs.
@@GunsNGamez Morally? Have either of you even watched MMA to know the rules? You keep fighting til the Ref stops it. Many fighters have eased up on their opponents and lost as a result when their opponent recovers. Fighters are told by their camps, by the refs, not to stop until the ref stops it. "Fight to kill"... LOL STFU.
@@damastashonuff640 you basically said the same thing Troy said... "Fighters are told by their camps, by the refs, not to stop until the ref stops it.", but still we admire those fighters that do stop when the opponent is cleary out, even though that's not, according to you, what the ref and their camp said.
Hey bro you got some good fight analysis and nice videos. A small tip if I could. Give a little bit more time at the end for the point of the point to seep in. The last thing you say in number 2 for example about how the guy was practicing evading defensively even though he was unconscious. That's some serious shit, and if you milk that a little bit longer it will have much more impact as far as the video is concerned. A good way to make each ending statement seem more impactful. Even just giving a few more seconds for someone to think about what they just heard before moving on to next point without analysis, it's a small dumb thing that will help your videos like this a bit.
