Who could beat Roy Jones?

[Primo Carnera]

Is there anyone from 160-175 who could beat a prime Jones?

He was great great boxer but his chin did not match his other qualities. He relied on freakish speed and reflexes but as he moved up and down in weight and got older the speed lessened and he had to rely on a chin that he did not have.

So I think had he had fought a Gerald McClellan a Nigel Benn or a Julian Jackson they may well have knocked him out cold

As much as I like Nigel Benn, and Benn certainly used to apply ridiculous amounts of pressure, at that time, I would see RJJ being way too elusive and skilful and giving a bit of a masterclass frustrating Benn .
Like has been said before, there are a few that could beat RJJ, but whether they would is another story.
Maybe at LHW, but Roy was a MW & SMW in his prime imo.
