imo. speaking specifically on UFC. they have no structure for climbing the rankings. since the rankings dont mean shit, the belts dont mean shit. especially the new lightweight title. its prize fighting like boxing. its athletic but i wouldn't call it a sport. all the major sports in America (even pee wee sports) are structured up to who plays for the championship. those are sports to me. if/when the Olympics pick up MMA, they will present it and organize it as a sport.
