I do think Chavez has hit a physical maturity and has really grown into weight, fights tall and dedicates to body well now. He's had a fair share of padding but is smelling less like talc powder and has improved. But I'm picking Rubio. He takes flack from shelling up vs Pavlik and frankly deserves it but I think that also resulted in recent momentum. He has good pop, solid experience and is a pretty capable mover. This is actually a solid scrap but lean towards Rubio finding the holes in Chavez jr defense and outboxing him.....but he better win with his own judges
