This was him talking about RJ after the first Tarver fight:
"He looked human for a change in his last fight against Tarver and that's given me confidence that I can beat him."
Basically admitted he had no shot against Roy in his prime.
Calzaghe in 2003 right before Tarver and after Ruiz:
“I’m a big Roy Jones fan and to be honest, he’s the only guy in the world that I really don’t want to fight. He seems to be the perfect fighter and you just can’t hit the guy. Look at what Jones did to Richard Hall who then fights Dariuz Michaelczweski and bashes him up for 11 rounds. I like to watch Jones fight and see his moves. He carries an aura that he takes into the ring with him. It’s 100 percent confidence and he knows he’s going to win. You can tell that he doesn’t take his talent for granted though because he obviously trains very hard and keeps in tremendous shape.”
