Pirog or Golovkin. Macklin isn't coming off a win and bar Sturm, Elcock and Asikainen, has looked horrible in every fight he's had at 160.
I like Chavez Jr. Sure he has been horribly overprotected, but he usually provides good value in a fight and is worth a watch. But he isn't gonna fight Martinez in a million years* *Unless Martinez gets sparked out by Macklin or someone else in the future, then he might fight him.
