mickey Garcia. Mexicans are always guaranteed to beat Puerto Rican fighters fact. not to mention mickey is a much better talent. remember what chavez did to Rosario. mickey does the same.
Mikey has only competed at that weight 1 time against a solid fighter but that does not determine whether or not he can just beat everyone ever. I will give Rosario the edge because he fought 18 years in that division. Imagine 4 years ago me saying that Broner vs Pacquiao would be a blow out because Broner beat Paulie Malignaggi at 147. I would be rightfully made fun of. Mikey has to find a division and stick to it.
rosario he fought in a very stacked / very talented time period at lightweight / fought a whos who of fighters. if he was good enough to beat bramble and randall he is good enough to beat garcia
love me some mikey, but i got to go with chapo. chapo held his own vs a card carrying top 25 atg and smashed some fighters that would beat everyone on mikeys resume.
