You can't say you're the best when you don't even hold a single title in the division.

WBC champ Witter haqs only ever been beaten once. By "Super" Zab Judah. When he had to lose 15 pounds in 2 weeks.

He also never beat Cotto at 140. He has to win the titles to be the best. Otherwise his claim to being the best is as good as mine.
