Poor decisions or not, fact is Oscar is 0-5 in super fights!
Trinidad was a poor decision.
Mosley 1 he lost
Mosley 2 was a poor decision
Hopkins he lost
Floyd he lost

These fights are his only super fights, Whitaker and Chavez were past their best and Quartey although unbeaten at the time isn't on the elite list.
To his credit he has fought the best out there but has no big W next to anyone in Superfights!
Kellerman is probably right!
