The title is true. Broner jumped 2 weight classes. He won the title his first fight at 147 against Paulie. Went on to fight 2 of the top fighters at 147 in Maidana & Porter.
If GGG had the balls that Broner has.......he would jump to 175. Fight Fonfara, Chavez Jr, Stevenson etc.
Dare to be great. Something GGG refuses to do.
