Canelo versus GGG: Who wins?
This clash is being touted by boxing experts as the biggest clash in the 160-pound division since the historic night 30 years ago when "Sugar" Ray Leonard defeated "Marvelous" Marvin Hagler via what was a controversial split decision. "But most importantly he is a great dad". His flashy performance earned him a unanimous victory, winning all 12 rounds on all three judges' scorecards, outlanding the bigger man three to one. "We've seen the best of him and I think people actually know - and this is a big factor - he is just human". Meanwhile, GGG will try to maintain his distance, as Canelo's optimal range is half a step closer than Golovkin's. There were moments in that fight where he looked to be struggling. How has GGG gotten old when he hasn't taken any damage?
