Sadly, I pick Oscar by KO at either weight. But Chapo is live at 135. At 140, its basically a mismatch.
I think at 135 its a real war. I just feel that Oscar being the bigger man would play to his advantage. De La Hoya KO 9 in a classic.
I don't know about 135... Hoya was clearly very good, but he also didn't face much at that weight, certainly no one approaching a prime Edwin Rosario I agree at 140... Rosario still had a hell of a punch but he was not durable at all there... Hoya knocks him dead up there
