Most fighters have learned, but natural would be Duran,Tyson. Hagler would be half and half . Hearns was learned and so was Ray. Ali was learned. Foreman learned. Fury surprisingly natural I think.
I agree 100%. Big difference between athletes and guys that were born with that special trait. Hopkins and Toney especially were born to be fighters.
Actually id rate James Toney as one of if not the greatest natural born fighter in the last 40-50 years at least.
