Conteh`s left hand was amazing, I watched a film study on it, he used to win often with one hand like De La Hoya because he had a damaged right hand early in his career, Conteh was better than De La Hoya p4p, but Roy`s right hand counters would give him an advantage and I feel he would of beaten Saad whereas Conteh lost twice to Matthew, good fight.
Going with RJJ...but this is Lightheavy, where Roy's chin on the Richter Scale is not impressive. And we are not talking about "same day weigh-ins". (Richter Scale: A numerical scale for expressing the magnitude of an earthquake on the basis of seismograph oscillations. The more destructive earthquakes typically have magnitudes between about 5.5 and 8.9; the scale is logarithmic and a difference of one represents an approximate thirtyfold difference in magnitude.
