Body shape has little to do with hand speed and power. Typically poor body type is nothing more that a lazy diet and skipping certain exccersises. As for power tell that to any of the world strongest man people. Speed yeah smaller people tend to have faster hands I think we saw that with JDS but Mir's hands and not any faster than Roys and Mir cannot punch as technical as JDS. Roy will stand and bang a round or two than bull doze him and than steamroll him into a pancake for either a decision or tapout due to man boob suffication
