Every promoter / promotion favours their fighters, hundreds of fights have swung the promoted fighters way because they are the promoted fighter

The promoters have a business to run, if their money earners lose they could be massively out of pocket, could even end their business if their prize asset is on the wrong end of a decision

So it happens much more often that they are on the right end of a decision

Some fights are close that perhaps should of gone one way but go the other, others are blatantly bad decisions

Now fighters can be more protected depending on their standing and earning potential

The kilts with wlad took this to the extreme , wlad would generally win a decision / get a knock out and all they had to do was let him hold and lean, both of which are against the rules , and they didn't mind that it was extremely blatant and regular because the German public would still pay

The fights were never pre planned but the ref and officials were well aware of the job they needed to do to earn they type of money they were earning
