Well you basically have to guage Lacy's entire worth as a relevant contender by the fact that he got his ass beat by Calzaghe. I really think he was kind of shit in hindsight, and while his chin was maybe a bit better than Echols it's not by much, certainly not enough to take his punch. Omar Sheika had Lacy all over the place and arguably beat him, there was another low level journeyman I cant recall who had him badly hurt.. Can't imagine Echols wouldn't have landed big first and therefore won by KO.
