Has there ever been a more dominant performance ?

[IamInuit]

To name a few,

Pea/Chavez
Hearns/Leonard until the bull kicked the door in
Cal/Lacy
Robinson/Armstrong

were all much more dominating really. This fight was more dry dominance

Calzaghe vs lacy is nowhere close to being the best two fighters of a generation I'm talking about super fights only

Hindsight did not appear in the question. It only became a non super fight after Joe throttled him. Then Jeff became a bum. Anyway I named a few and am not going to debate something else entirely.
