Re: What percentage of fights are rigged?
I do not believe that any fight is rigged where a fighter is paid off to take a dive. Due to the upside of a big win (and the downside to the loss), the finances would never make sense to a fighter, who actually has a chance to win, to be paid off in a fight.
However, what does happen is the hometown promoters 'take care' of the officials and sanctioning bodies to hopefully give their fighter the upper hand. This happens everywhere, with scoring being so off from what the public sees. However, Germany is notorious for taking it a step further and having refs completely control the fight to make it very hard for the opposing fighter to win. Yes, Randy Neumann is a great example of one instance, but there are many others (pick any Ottke fight).
