I suppose you mean all time.

Heres some matchups that are worth thinking about.

Foster @ Light Heavy
Archie @ Light Heavy
Hagler @ Middle
Calzaghe @ Super Middle
and the ever famous Dariusz match that never was.

Foster @ Light Heavy = Jones by TKO

Archie @ Light Heavy = Jones by UD.

Hagler @ Middle = Jones by UD

Calzaghe @ Super Middle = Jones by UD Calzaghe would be dropped at some point in the fight with a straight right.

and the ever famous Dariusz match that never was. = Jones by comfortable UD.
