Roy Jones Jr vs Joe Calzaghe in 2000ish

I've changed my mind on this a lot.

I see Roy winning the early rounds, he was still too fast for Calzaghe. I see Roy looking very good for the first four-five round, but after that I am completely at a loss. Will Joe be able to come forward through all the gun fire? Would he make it? Roy in his prime hits 10x as hard as this version. However the biggest question from then on is when Calzaghe makes it through which he likely would, Roy never really stepped on the peddal a whole lot early when he had good opposition hurt, would Roy be able to deal with what Joe brings? I think the 1994 version of Roy could deal with it fine, but I am not sure the guy who had troubles with Montell Griffin and Eric Harding was that same guy. He seemed too bent on virtuoso performances that he didn't have that fire anymore. I thought Roy showed great heart against Antonio Tarver in their first fight, but besides that I haven't seen that heart since Roy fought James Toney. He trusted his instincts, he fought smart, he moved a lot, he threw the right combinations at the right time. However later on He thought too much, and I can't see Calzaghe winning the fight, but I see it being a very close fight that Roy has a lot of troubles with.
