Who is then? Jones? The guy with one fight in the division? Ngannou's the most proven heavyweight in the world and left the UFC with the title.
He made 30 mil in 5 months guy.
He made more fighting Floyd. And his next 3 fights were definitely a lower salary.
He fought one of the top 3 boxers in the world, even Conor didn't do that. No one has. The Joshua fight is what everyone expected the Fury fight to be. That doesn't mean he's suddenly gonna start sucking in MMA. And his opponent is getting 2 million, so what do you think he's getting? No reason for him not to come back for an easy paycheck.
