Dull? Dull is an understatement. Outside of Crawford, Kov, Chocolatito, and a few others...I don't see anyone out there that I would pay to watch their true skill.
Floyd aka Money Mayweather is not coming back as there is literally nothing left to prove. Beating GGG does really mean much in the grand scheme of things. He has already shown Pacquiao is not in his class. He has outclassed Canelo already despite one of the judges being blind who made it a draw.
