I'm starting to question if a person should be considered an ATG that never unifies a division.

Let's take Pacman for starters. Undoubtedly will go down as one of the best of his era. Some will say ATG. IMO he is the most exciting of this era, hands down.


1st chance to hold 2 titles is against Sanchez, ends in a draw
2nd chance to hold 2 titles is against JMM in 2003 who held 2. Ends in Draw.
3rd chance to hold 2 titles against Morales -both vacant, he loses, unanimously.
Immediately gets a belt after loss
Takes on Cotto for his WBO & a vacant belt. He wins. Now some could say, well he won 2 titles, however he never defended this belt. A diamond title, so does that count?
Pac wouldn't fight again for multiple belts until Floyd. He loses.

Explain from your POV how it is possible to be an ATG in several divisions he never unified?
