If Money boxed in the 80's and faced Hearns, Hagler, Sugar and No Mas, it is more likely he would go 0-4 than 4-0. Money is the best of the past 21 years but not the best of all time. It's not his fault. He fought everybody out there - although De La Hoya and Pac were past their prime. But you can't make him GOAT when he never faced the Fab Four. Hearns probably the GOAT in the debutante round. If Money did what Hagler did then crown his ass. No way he could have danced out of that. He would have had to take the punishment, survive and have enough left to take control. What Hagler did was epic. All 50 wins combined by Money don't come close.
We will never know.
Fuck you, Tiger
