This is an agenda thread (I don't mean the original poster meant it that way, I don't know), Calzaghe fans are gonna for the most part say he ruined him, anti-Calzaghe people are going to say the opposite.

Its probably somewhere in between like some have said. Lacy had some glaring flaws that got lost a bit because he looked like a killer. If that had been him against Kessler then Mikkel would have probably done a number on him (probably not as bad as he wouldn't have been as busy as Joe), good technical boxers with fast hands, fast feet, good footwork, etc. were always going to give him problems.
