GGG's signed a six fight deal worth $100 mill at the age of 37 when well past his best and in addition to his numerous endorsements his fights are broadcast in well over 100 countries and he has sold out all over the US, Britain, Japan, Monaco etc. He's done now but he's been one of the sport's biggest stars for years and far bigger than some of the other names mentioned here.
Come winter it will be Fury, AJ, Wilder & Usyk. Menawhile the ginger midget Canelo will be crying in the corner claiming he can beat Bivol whilst still beating on washed up brits.
Two of my top 5 cash cows made the Forbes top 50. No sign of Tyson fury or Gervonta Davis? 5. Canelo Alvarez Boxing $110 M $100 M $10 M 28. Anthony Joshua Boxing $53 M $50 M $3 M
Canelo and Joshua only, they are giving opponents life changing/tax bracket changing money. No one else (currently is doing that)
