I like how everyone thinks there is this mystery line of sponsors just waiting to pay fighters $10,000 to advertise on them.
When in MMA was super hot a lot of odd ball companies tried throwing money at the fighters for sponsorship. But today is a different landscape in MMA and it isn't that easy or as lucrative unless you are a big name. Hell, about 5 years or so ago a fighter from Bellator, fighting for the championship belt was on Sherdog looking for sponsors. Grant he didn't have much of name, but either do a lot of these fighters.
I think what PFL is doing is smart. I'm sure they also have to sign off on the sponsors. Maybe down the road it will lead to a couple major sponsors sponsoring the red fighters and a couple major sponsors sponsoring the blue fighters. Then divide it out on some scale.
