Honestly...The very best i could imagine...

Roberto duran - Julio Cesar chavez Lightweight..

Floyd Mayweather - Barrera/ Morales/ Pac.. Super featherweight..

James Toney - Bernard Hopkins Middleweight..


But with the floyd thing...Can you imagine how much respect he could have earnt by this stage of his career had he stayed at say super featherweight and fought with all the big names down there...

Barrera marquez pacman barrios morales .. I think he could have gotten so much more respect and truely great legendary fights under his belt had he actually stayed in one division for a prolonged time and unifed a division or maybe a few titles..

Roy Jones jr - Tommy hearns Middleweight... I remember manny once saying he thought tommy would give roy all sorts of trouble.. And he probably would.. But at middleweight i think roy might have stopped him..

Peace
