They already have a feeder system...THE REST OF THE GODDAMN PLANET! Seriously, there was an article the other day about how the UFC was poaching Asian fighters simply because they could. There's no regulatory body making sure the org doesn't get screwed when their best fighters head off to Vegas. Why would they bother setting up lower tier shows and taking the rest when there are dozens of small businesses doing it for them? The whole situation is kind of shitty. But, it won't be this way forever. Like a threat to an organism's survival, MMA will either adapt and protect itself from further incursions, or it will die when it fails to evolve.
