I'd LOVE to see this fight. I'd favour Lopez but on a split decision. I think he is the better fighter but Calderon is a southpaw spoiler.His elusiveness would get anyone problems and has he showed v the monstrous Cazares(who was like 140 pouds fight night!) Calderon can take a punch so he should be able to withstand the sharp shooting and accurate power punches of Lopez. I'd favor Lopez for sure though.
