12 round fight scores that might have gone the other way after 15 rounds

[IamInuit]

Really cool question.

Hagler would have beaten Leonard. Rays legs were gone.
Shit Chavez may have stopped Martinez
Take your pick in the Manny/Marquez series
Morales/Manny 1 maybe

Its also interesting to view it the other way.

For example Hearns would have won going away against Leonard in the first fight if it were 12.
