I loved watching Ricky fighting, but if this fight had come around then I'd been watching through my fingers!! Julio was an absolute beast and Hatton would have walked in to the Jaws of the beast. JCC wins by 10 rounds KO, with Ricky on the floor, crippled by the body shots.
See the Rasario fight. Chavez at 140 was still a formidable fighter. Hatton was simply a good fighter. Chavez would wear down Hatten the way he did Rasario, stop him within 12 rds.
I think this would be similar to Chavez vs. Haugen, just that Hatton has more respect for Chavez and it would be a 9th round stoppage instead of a 5th.
Hatton would be competitive for the first 4 rounds. After that, it becomes a one sided beating in favor of JCC. Chavez TKO 8.
