I gotta go with Wlad/Byrd. True that Lacy was thoroughly dominated and didn't win a round, but Calzaghe just doesn't have the power to crush anyone the way Wlad crushed Byrd. The knockdown that ended the Byrd fight was just brutal. I didn't see any one thing in the Lacy fight that looked that awful (for Lacy).

Lacy got soundly beaten in boxing. Byrd got beat the fuck up.
