As of now, guys like Canelo and EUBANK and kyrtov can all fight easy fights, like broken Martinez or broken b level Yuri foreman... But once GGG holds all the titles, the guys who can no longer boil down to 155 will be forced to go thru GGG if they want to make a name. It'll end being Sadam Ali, Erickson Lubin or Errol Spence that will finally best GGG
Nah, Ali Raymi will rise like a phoenix from the grave and double KO Canelo and Cotto. Then he'll KO Golovkin and initiate a new era of Shariah in the United States.
