I think Julio has the potential to clean up both divisions. His natural build is definitely towards that of a middleweight so 154 would probably be most natural for him. Considering he has virtually no amatuer experience he is an incredibly smart fighter, patient when he needs to, and defensive if that is called for but when he unloads he is like nobody in either division.

I'd love to see him in with Margarito in a big slugfest. I'm confident Julio would be too strong and big for Maragrito who failed when he moved to 154lb. Julio is the only guy on the horizon that I see challenging Mayweather.
