I think before this fight happens Cotto will vacate the belt. Partly due to Golden boy not wanting Canelo to fight GGG if he should win the middleweight title.
Cotto has a harder left hook than Kirkland. At the same time, Cotto doesn't have much heart when the going gets tough. Margarito v2 by KO.
Golovkin beats them both..................Cotto will never come near Golovkin. Golovkin knocked Geale out in the 3rd round, so Cotto is fighting Geale at a catch weight! No title should be on the line in such a fake fight. If Cotto wants to be thought of as a middleweight champion he should fight at 160...................Cotto is a coward...............he runs and hides from Golovkin..............and Alvarez will not fight Golovkin either.............
