I hope your kidding at 135 PBF was faster than Shane by more than as a welterweight, also PBF was pretty hard puncher for a lightweight, and he as good of a jab as anyone back then to go along with a nearly perfect defensive way of fighting... If Mosley couldn't get through Forrest's jab he wouldn't be getting through PBF's. I think Floyd outboxes him with a clear decision which means by about 3-4 rounds.
