Let's break this down for a second. Even with the reported $10k to show $10k to win increase in first time UFC fighters, let's just fucking break this down.
An average UFC fighter MIGHT get three fights a year, despite the fact that there are more shows then ever. let's say this hypothetical UFC fighter goes 3-0 during this time with no bonuses, because bonuses a lot of the times are like awards (Academy/Emmy) and are given not so much on what was performed in the cage, but on who you are (not all the time, but enough of the time to bring it up).
