The rush was supposed to have been done by suprise as Emin who had a habit of jumping people in the past and did so there , If someone gets the slip on you with a tackle odds are youre going to to fall to the ground.the If one doesnt manage to regroup extremely quick the element of suprise can give the attacker the ability to impose his will even if the person he is attacking could defeat them on what would be deemed as "fair" conditions.
As Someone with basic grappling know how im aware the various anti grappling techniques are for the most part rubbish so lets not go there lol
Granted one could make a case for people who spout this anti grappling as crack pots but recall the Gracie's had a similar attitude where they believed one only had to learn bjj and they had techniques that would nullify stand up completely.
In the Wc case and the Gjj case i dont see it as so much of ignorance. I see it as being stubborn and toegomaniacal to admit they dont have all the answers and as competitions and online videos have shown people who adhere to a belief like this end up having to eat crow.
I recall my former bjj coach noted how a Gracie ( cant be bothered to remember which one) remarked how adding striking into the mix changes everything in regards to how you fight with your bjj in other words it makes it a hell of alot more difficult to do in a anything goes environment.
And it does so goes grappling when its added into the realm of striking.
if this bjj guy is put in this hypothetical situation and he doesnt have experience against strikers or has much striking experience himself there's a very good chance he could get dropped before he has chance to do much. or beat up if he fails to keep the guy on his back or nullify his punches from the ground.
this video highlights it as the mt guys clobbers the bjj guy off the failed shoot.

now one could make and argument for him being terrible at takedowns but shoots fail regardless of who you are and one small mistake like in that vid can play right into your opponents specialty.
We have a show over here called Bully Beatdown where they have mma fighters engage in actual mma matches with stuntmen .They have a grappling round where the mma fighter is supposed to submit the stuntman five times in the round before it moves on to a kickboxing round.
Jake shields has been on there more than once and he failed every time to submit the stuntmen five times in the given round . Jakes considered to be one of the best bjj guys out there yet he couldnt put away stuntmen who clearly had no grappling experience.
Another mma fighter named Tony Bonelleo was nearly kod by one of the shows actors in his match.
To me this is just a case of **** happens.With live sparring./fighting if you dont do the littlest thing right you screwed and with all things martial related its easier said than done even including submitting someone who isnt trained or defending the take down against someone who wouldnt know a proper shoot to save their life. Unfortunately goof ups like this can be caught on tape and be a source of shame for the parties doing badly.
Granted the difference between these mma guys and Cheung is we have more evidence of the fighters not preforming so poorly so we can compare and contrast. With Cheung we only have one clip as you noted.
However i wouldn't entirely write off Cheung. Though of course i wouldn't call him a world class fighter either as he was simply known for being a good scrapper in his youth and that's hardly grounds for being considered elite in any important means.
Lets be honest with that clip we saw a much smaller fifty year old man either get taken down or slip on the ground with a much bigger younger gentlemen who sneak attacked him . and possibly got put in a headlock from the looks of the video so the fight for some odd reason started attached in the grappling range.which is considered to be wc weak point Then of course the rest of the vid is hard to make out before it abruptly cuts out as quickly as it cut in.
Since Cheung obviously wasn't a professional fighter and did not have the years of conditioning and experience people in that sport do he should understandbly at the age of that vid not exactly be anywhere in prime shape for fisticuffs, Hell im sure what ever training he was doing at that period had tapered down in intensity to considerably.
I think if anything the vid says more about Emin as he couldn't put away a small old man who was an ex brawler many moons ago and had to resort to jumping him to start with. I sure as well hope i could easily defeat a smaller fifty year old even more so if i have the advantage of attacking him out of the blue.Further i believe Emin claimed to have extensive experience in Turkish wrestling so the fact he couldn't use this to wrap cheung in a pretzel and pound him out is even more funny.
No matter how you slice it its always gonna worse for you if you attack someone smaller and much older.
