Was Jeff Lacy a fake or did Calzaghe ruin him?

[Andre]

Lacy was a good strong pressure fighter.

Calzaghe was simply in a different class and exposed him.

The beating Joe gave him and the shoulder injury really has fucked his career up.

True , but like Scrap just said though ,it starts and ends in their mind first.
Its a hard road back from there if your core belief has gone out with it,then more physical trouble usually follows.
