Victor Polo had 5! Manuel Medina and Glen Johnson got plenty of title opportunities as well in the end.
What a joke these Alphabet belts are. :-( Glen Johnson had 8 :!: Firat Arslan is 2-3 in last 5 fights. All 3 losses were title shots. Miguel Cotto has had 5 title shots. Won all of them. Floyd has "challenged" for a belt 8 times. If you count the Maidana and Alvarez unifications then that makes 10. Pacquiao has had 8 and if you count his ball-buster unification with Sanchez then that makes 9. Paulie Malignaggi managed to get 5 shots. Zab Judah had 8. I am not including unifications. I got kinda cunfused with those.
