No. Not if people don't want to watch them. What if a 95 pound guy was really good at MMA? Do we have to make a new weight class and give him a chance to showcase his talents as well? Of course not. Nobody gives a f*** because the average guy would still beat the crap out of him.
Too many belts waters down the significance of having one. I'm not willing to pretend a 115 pound man is of the same caliber as Anderson Silva or GSP.
I hope you don't think that the average guy can beat the lower weight classes. That would be pretty funny if so.
