I think Andrade can and probably will eventually be fighting at 175. Who knows, maybe there will be where he makes his mark. At any rate, I don't think there's much of a size difference here, despite Andrade's competing at 168 while Gonzalez has always been a light heavyweight. Who do you pick in this fight that couldn't possibly be anything less than a war?
Based upon styles you might right away assume this would be a really entertaining fight. I doubt it it. Both guys are very slow on their feet and handspeed isn't much better. Gonazales is old and @ 175 Andrade would just be bigger and probably slower. Although both are of the come forward syle of boxing both are very limited. I think it goes the distance with a lot of sloppy shots missing or being blocked.
I picture a fight sort of like Ruvulcaba vs. Mendoza. Man I wish I could find my copy of that fight. That was a crazy war.
