I have to second what most people said, I think Floyd is much more in tune with his mind and body, ala Bhop, than a Roy Jones.

I understand the comparisons between Floyd and Roy, both being insanely gifted virtuosos, but I think Floyd is a different animal. In my eyes, Floyd has been declining ever so gradually over the last few years, but what makes Floyd a true great (probably the greatest) is that he's successfully adapted and changed to suit his slowly declining physical attributes. We've seen him start being much more economic with his movement, staying in the pocket more and minimizing energy expenditure, now that he doesn't have the legs he once did.

Like someone else pointed out, Floyd is much more comparable to Bhop, in that he's not a guy who relies on insane speed and reflexes. He's a ring genius who wins by being 5 steps ahead of his opponent. So I don't think we're likely to see a sudden crash like he did with RJJ.
