Which boxer is hardest to beat currently?
Wlad seems to be a league above the others, but one punch can change all of that. Mayweather used to be extremely hard to beat, but I think he's slowed down quite a bit the last few years. Same for VK. Bradley is good but not unbeatable (Pac did it according to most).
As much as I dislike the man, I don't see Ward losing to anyone soon. Certainly not at 168. Too skilled, too much ring IQ and always the hometown edge.
