You can pull other examples,and still see the same trend. Even against Mitchell, he was only batting 22% total. As I stated Pacman misses lots of his jabs but is usually over 40% with his powershots. Pacman landed 50% of his powershots against Mosley and over 40% in Marquez 3. Williams was usually 20-30%. Well, Williams' punch output ranks amongst the highest in the modern era for his weight class, but he didn't really seem very effective with it like Pacman or Calzaghe. He picked up some contested decisions based on activity but rarely broke quality opponents down and was always left open to counters, leading to two bad defeats. He may have landed a few more punches than Martinez, but in large part got batted around He seemed to have great stamina for punching, but rarely used movement or footwork. Too bad he never channelled his conditioning until that or develoepd a jab.
He was good but too bad on defense to merit all the hyperbole going on in this thread. Wide open, lazy jab, in fact all of his punches seemed lazy/slappy to me. Extraordinary physical specimen but came across as uncoordinated and herky jerky in the ring. Great stamina, tough, tough guy. He was a joy to watch and I miss having him in the sport.
