Arguably the two fastest lightweights who ever lived. Who wins? I think Laguna wins CLEARLY, tbh. Better technically skilled, better stamina, and overall just a more substantive fighter.
To me, Camacho's skill level was quite low in comparison to his athleticism. Someone like Pacquiao has a similar issue. Compare him to somebody like Floyd - or Laguna, in this case - who was brilliantly skilled and athletic as fuck. Camacho's footwork was extremely quick, but quite basic and repetitive IMO, and Laguna would both be able to keep up with him, and predict what he was going to do next. Laguna didn't have the best left hook, but his right hand was magnificent. Once he gets his timing down, he should be able to hand back and walk Camacho on to those nasty, slashing inverted one-twos, and as he eventually would, as the aggressive fucker he could be, walk Camacho down with them.
