A lot of any sports fans are racist or all other kinds of stupid, it doesn't mean there is anything systemic going on. Floyd is somehow implying that black fighters are actually held back on account of their race, which is fairly priceless coming from him.

I was going to add he may have more of a case with the UFC as I have thought the same thing, but then I'm not sure any fighters they've had were ever hyped as much as Rousey was, might have just been a sales pitch to try and get as much crossover attention as possible.
