As we all know Sugar Shane was basically unstoppable at lightweight, but Broner was a beast also. Who do you think would win this fantasy warfare?
Broner is durable, the Maidana fight proved that. But Sugar at 35 was a complete destroyer. The Reach, Speed, Power would prove to be too overwhelming for AB. Sugar KO
Broner would have nightmares of a green eyed monster. Like when Frodo puts on the ring and he shits his pants when he sees the eye of Sauron. Mosley completely humbles Broner.
Mosley was explosive at 135 and in his earlier days of 147. He'd probably have been Floyd's toughest fight of his career had they fought at 135.
I remember in 1998, Mosley fought around 5 or 6 times that year en route to winning the BWAA fighter of the year. He was some kind of fighter at 135 lbs. Power in both hands (he had a ridiculous KO percentage at LW,) fantastic handspeed, he was the real deal. Broner doesn't throw enough punches in general so i don't know how he'd keep someone like Mosley off of him. I'd imagine Shane catches him inside 6 or 7 rounds. Mosley is a HOF fighter that did some great things north of 135, but at LW he was definitely at his best and a H2H nightmare with anyone in that division.
