Dubois is obviously a big puncher with both hands, but whenever I watch him land on somebody, it seems like the left hand does much more damage than the right hand. Miller and Hrgovic, two iron chinned guys, seemed to take the right hands fine, but were getting stunned by Dubois' stiff jabs. Dave Allen sparred him and said that the jab almost took his head off, but the right hand didn't have the same effect. I don't think I've ever seen another fighter whose jab is more powerful than their backhand.
