Calzaghe wouldn't ko Trinidad either, IMO there are a lot of fighters who wouldn't have been able to KO that version of Trinidad. Also I don't think Roy would be beaten to the punch as much as Calzaghe would dictate the pace and not allow Roy to get anything off by bombaring him with punches. I think if Calzaghe fought at a slow pace Roy would beat the shit out of him, but thats not Calzaghe's style.
