I'm not an expert, but Takada was a pro-wrestler in Japan, and was a hero to lots of fans. He is not a good a fighter as some of his opposition so he doesn't have a good record. In order to make Takada look like the hero he was in his pro-wrestling days, the promoters try to fix fights so that his wins can draw a bigger crowd.
Some fighters do it ( I think Coleman was one of them) and some don't.
That's about all I know
