On that subject UFC just announced they're doubling bonuses to 100k per and introducing a generic 25k bonus for anyone who gets a finish but doesn't get a Fight/Performance of the night bonus. Still an absolute joke all things considered.
This won't do shit.
Fighters that are desperate for bonus are unranked guys on early prelims, and most people don't watch prelims, and they are already have plenty finishes on prelims cards because if you don't get finishes, you are stuck on prelims and apex cards.
If you have a rank, or more importantly, a belt, you are not going to war for 25k when you risk losing sponsors and brand deals.
You won't see a point wrestler suddenly turning into Rodtang for 25k.
We can even use the PFP champ, Islam, as an example. His second fight on the UFC he wanted to stand on equal against a kickboxer Adriano Martins only to get slept on the very first round.
Since then, Islam never went to war again, he is a decent striker, but he stays out of range, always defensive, and strikes only when he can also apply his chain wrestling.
We love brawlers, but fighters need to win fights to stay in the game, and if being a leg humper gets you Ws, then a 25k bonus won't do shit to change that.
