Roy Jones is done IMO. JC, injury free, is pretty much at the top his game. Age was no matter when he fought Lacy. Injuries are his biggest worry. If this fight happens I think Calzaghe will retire Roy. A part of me wants this cos I dont want Roy trampling all over his own legacy by going on too long and ending up like Tyson.
In his prime Roy JJ would have beat JC. Of that I have no doubt. Now though? JC hurts him.
