Can you be an all time great if your best win is against Jeff Lacy?

[ono]

Calzaghe is an all time great, Kostya Tsyzu I don't think so.

Well the thing with Kostya is that after he first lost as a pro he came back and unified all the belts by fighting the best guys in his division. We don't know if Joe could have come back from a loss in such a way and never will and we know he never fought the best in his division.

Joe has a good record and retired unbeaten but I'd say coming back from a loss and dominating the division is just as great.

But surely it's better to not have lost in the first place. It's a baffling logic that i hear all the time. Weird.
