Would Hatton be too big and strong for Rosario, or would Rosario have too much firepower for the hittable Hatton? Personally, I just don't think Ricky has the chin to stand up to Chapo's best.
Hatton grinds him down and smothers Rosario. Hatton takes a clear but competitive decision. 8-4 7/5 type....
If you take the slowed down, 140'ish Rosario from the later half of his career, where he was already noticeably declined and having substance abuse issues, than Hatton more than likely stops him. But if you were to have a 130/135 pound and younger Rosario I'd choose him to take Hatton out, even if he were to come in several pounds lighter than Hatton.
An even fight for the first half , then Rosario takes command. He starts to breaking Ricky down before stopping him in the tenth.
