And most of those "top" batamweights outside of UFC barely make any money and are mostly anonymous. What a dumb analogy you make. UFC does not need to employ every fighter alive to be compared to the NFL. They already have a bloated roster. They only need most of the top 20-30 which they already have.
UFC is compared to the NFL because its brand is synonymous with the sport and recognized as the place where the best are fighting or playing. Compare UFC to the Champions League. Not every great player in the world plays in the Champions League, but 90% do and that is enough. And the 10% that don't want in.
