Marquez didn't look to good at the weigh in. Wondering why he doesn't move up to 126, he should be able to bring his power one div.(might be a bit late in his career though) IMO Lopez has taken too much head-punishment in his young career already. If Martinez does not blow Barker away, we will have plenty of threads on how overrated he is.
Rafa looked good at 126 but he's probably more suited to 122. His power is such that he's going to hurt anyone in or around his weight class. Hope he can pull it off - it'd be a very impressive victory. JuanMa doesn't have much of a defence but that's what makes him worth watching. I think he still has quite a bit left. As long as he stays away from Gamboa, he should be okay. I don't think there's much chance of that tbh, Martinez should completely dominate.
