Here is the thing, triangle theories don't work in boxing. Just because fighter A struggled against fighter C, but fighter B didn't struggle with fighter C doesn't mean fighter B will beat fighter A.
Case in point Marvin Hagler got put through hell by Roberto Duran and won a close ass majority decision over him, Tommy Hearns got Duran out of there in the second round. By the logic you are using Hearns should beat Haglers ass, but Hagler got Hearns outta there in 3. Because styles make fights bro.
