Ranking systems are not new in combat sports, and ONE championship is no longer a new promotion. This raises the question of whether we should hold the ONE championship to a standard similar to that of the UFC or top-level boxing. If we were to hold them to that, a suitable ranking system would be the minimum we could ask of them.
However, they are failing in that regard and failing badly.
The MMA fighters signed to ONE Championship seem dissatisfied with their inactivity and being outright ignored by the matchmakers.
