I think it's nuts to try and just put them into a top 100 list... I wouldn't even know where to start.

Ricardo Lopez
Joe Calzaghe
Bernard Hopkins
Manny Pacquaio
Juan Manuel Marquez
James Toney
Sugar Shane Mosley
Roy Jones

Instead I would rate them as follows. In a all around career look.

Lopez
RJJ
JMM
SSM
Hopkins
Toney
Pac
Joe
