I think Canelo will win some rounds but Golovkin has that fantastic workrate and Canelo doesn't. Canelo has had an awful lot of easy fights against guys much smaller than he is and has never faced anybody as big as Golovkin is (other than walking punchbag Chavez) or who hits anywhere near as hard or who brings it for twelve rounds. But Canelo will definitely have his moments. I expect Golovkin to win and to try and keep it at range, I don't think he'll want to get into an inside war or take too many big bodyshots. If Golovkin only wins by a couple of rounds expect a really bad decision. Canelo has years ahead of him as a Vegas/PPV attraction. Golovkin doesn't. I can definitely see these two fighting next Cinco too.
