Roy Jones (1999 - 2002) v Bob Foster (1968 - 1974)

[Ezzard]

His competition at light heavy was better than Jones' competition. And he fought the best that was around, which is all that he could do. Jones did not do that.

That's it. That's the key difference.

Foster was a true champ who won the title and said, "Come and get me." When he cleared out all the challengers he went after bigger fish. No shame in a guy smaller by 30 pounds or more, losing to those guys.
