Skill wise he is in a league of his own. He knows all the tricks and invented a lot of them. Even when he holds it is in a intellegent way, not like Ruiz holding or someone like that. He holds subtly with the arm thats opposite the ref. and throws short punches with the other hand and then immidiately spins out and some of the sh@t he does looks dirty and maybe it is but it works. But the way he does things isnt teachable. Hopkins is the definition of a guy who fights with his mind and is a genius at it. In terms of skill he top 15 of all time. In general hes in the top 25.
