Let's assume the PFL becomes a viable promotion that comes back year after year. The vast majority of the UFC roster won't make a million a year even with sponsors. And probably never will. Alex Nicholson wasn't. He was 1-3 in the UFC but may be a millionaire by the end of this year. Meanwhile the guys who beat him the UFC (Sam Alvey, Misha Cirkunov, and Jack Hermansson) will never see a million bucks during their entire tenure in the UFC. I'm sure many ranked fighters would make the jump. And what of this year's champions? You think they'll jump to the UFC for 50K/50K after winning a million? They would want to come back next season to win another million.
