You should learn to listen to people that disagree with you rather than assume you already know everything they have to say.
Here is a reasonable take on the issue, which disagrees with yours. I posted this earlier. You might disagree, he might be wrong, and that's fine, but it is at least an intelligently thought out response and not a strawman.
My first point was to say that people who were calling those who claim this was a fix "complete morons" are being uncharitable, and ridiculous. And vice versa.
Kay, for the record I always listen to the other side of an argument so I'm not sure where you're coming from with your first line as I don't believe I was in any way hostile or dismissive in my responses. (With the exception of the somewhat condescending Youtube comment).
I watched the video and he proved nothing and never offered a reason for what Rizen would gain from this. I was intrigued by his take on the first knockdown though having a trip involved but as he says himself you can't really tell from the angle in the video and Tenshin definitely got caught behind the ear getting rocked for the first time in his career so his reaction is understandable as it was a new experience for him.
The second knockdown which was clearly the most brutal and clean shot of the fight he's trying to make a JFK assassination "up and to the right" style argument which is clearly wrong cause while Tenshin did have his head turned the punch doesn't land behind the ear as he claims in the video but under the chin forcing his head to straighten up before snapping back, perfectly normal reaction.
The last knockdown he lost all credibility with me saying he's never seen a fighter losing there equalibrium from a shot behind the ear ( which is a KO spot, the temple is what takes away the equalibrium) fall and then try to get back up only to fall backdown again. This has happened in the exact same fashion it did with Tenshin literally 1000's of times. Watch a Boxing KO's video on Youtube and you will see it happen a few times in a 10 minute highlight reel. Or for an MMA example watch GSP Serra or Kongo Berry (off the top of my head).
This guy IMO hasn't been watching combate sports for long, (based on him confusing a temple shot with a behind the ear shot and his examples being very recent fights) if he seriously though the 2nd and esecially 3rd knockdown were in anyway unusual or suspicious looking, the third being the worst possible example of an unusual reaction.
I'm pretty much positive the fight was legit based on the fact theres no upside for anyone to stage it in that fashion and I'm also fairly confident had this fight taken place under the banner of the UFC nobody would question it.
This fixed shit comes up with almost every high profile fight outside the UFC and it's tiresome.
Him saying he's getting dropped by Floyd who isn't known for his punching power is also blatantly wrong and indicates a lack of knowledge of Floyds career. Tenshin weighed 137, when Floyd was fighting guys at that weight he was destroying them without also having a 10 pound weight advantage. Floyd was a big puncher before his hands became brittle and he changed his approach. Look at what he did to Gatti and Corrales for example.
