Enjoying a huge reach advantage is not the only reason Jones has not often been tested by the world's best at 205.

I do see what you are saying in that his skill levels are not virtuosic yet. It is fair to say that he will only get better with time and he is not near the level he can one day reach. A man's level of talent in any field is infinite, it is up the person to master anything that they spend their time with.
