Wasn't Kostya champ for 10 years and wasn't he one of the first to unify the titles in a long time? Like every belt? I would have,from this generation:

In no particular order
Hopkins
RJJ
MAB
EM
Pacman
Oscar
Winky
Shane
Calzaghe
Pongsaklek
Floyd
Tito
James Toney
Tszyu

That's all I can think of for now but I also believe that Joge Arce is only a few big fights away and I believe in a few years time,Cotto will be there too.Hatton too and I was no unsure over wether to include Castillo and Corrales?
