Man! I'm very surprised to have never seen where the link takes us in any of the many, many "Top 10 craziest boxing matches..." type videos that're constantly churned out. Just curious if anyone else here was aware of this? This content is protected As I've mentioned before, I do a lot of searching for fights on YouTube channels/Google, other video hosting sites that are based out of countries with writing systems that don't use Latin based script (I THINK that's a correct description?) as, for example, it appears they do not arbitrarily just throw the fights of/or with the name 마이크 타이슨 (Korean script) into the results when you search Mike Tyson. The YT channel the linked video is posted to is really, REALLY extensive. They've a ridiculous amount of full fights, ranging from the 1960's forward, many of which aren't easily found. If you cannot read Korean I suggest using Chrome as it's translation features are fairly easy to work with.
Yes, I've been subbed for a while. They have some rare footage (including amateur bouts) and HD footage as well (Canto - Park, Chang, Moon etc.) as you said. However, keep in mind they also regularly remove videos, so if you see one you really like, maybe download it.
