Rocky Juarez and Prince Naseem are both fairly short. Is this for your own amusement or are you trying to replicate movement in a boxing class? If the latter is true, don't limit yourself to smaller fighters, try and observe shorter fighters against taller opponents or opponents with larger reach advantages, regardless of the division they are in. Or if you are taking a boxing class talk to your coach!
