Well yeah better fundamentals, a great chin, a more defensive approach, he's adapted... But it's not as if Roy Jones is the odd man out here, there is nothing unusual about his condition for a 45+ year old man. Hell out of the people who have been fighting as long as Hopkins has, Jones isn't even in bad company. Not to mention the vast majority of freak athletes rapidly lose that in their mid 30's, most just retire by then, in any sport. Roy has just stuck around way to long as so many do. You may as well ask what Hopkins has that Chris Eubank or Michael Nunn didn't, for some perspective on the eras.
