I think he punches more like Foreman. Foreman didn't have that one punch knock out. Whether it was technique or what he just didn't knock guys out as much as he pummeled them into oblivion. Lewis has more snap to his punches and he really ko'ed guys when he hit them properly, same with Tyson. I think Ibeabuchi didn't have that crackle in his punches, he is like COtto or Foreman in that he would pummel guys and break their will, but I think the bigger gloves and fighting tough guys so early in his career stopped him from having that great ko ratio. Regardless he had that Cotto thing that he could punch beautifully to the body, and he could box decently, and he pretty fast along with all that strength.
