He probably didn't. But regardless, just taking punches is not a smart strategy and no fighter sets out to just take punches. If they could avoid them, they would.
No fighter is perfect, they all have weaknesses. What in part makes a fighter great is how they minimise their weaknesses and Golovkin was good at that. But having said that... He was relatively easy to hit, he was no Willie Pep that's for sure. His hand speed was decidedly average, though he was very accurate despite that. He had very good foot work, in terms of balance and cutting off the ring, but he didn't have very fast feet, not a plodder but hardly light on his feet, but I guess that's were his power came from, from having a strong base and being planted.
I was going to relate the same his speed really slowed down by his early thirties combined with his slower hands is how the latter part of his career fighters got to him more and easier.
GGG outlanded Canelo by alot in both fights and was only short by 10 punches in the last fight when he was old and gray. So if GGG'S weakness is his defense, GGG'S weakness is better than Canelo's strength.
Yep, ringside reporters had it 30 or more for GGG, 15 had it a draw, and 2 had it for Canelo. Thats not a good look for the supposed winner.
His biggest and basically only real weakness was that he took turns, shelled up when being attacked and waited for the opponent to finsih and then went back on the attack. He didnt punch with his opponents and didnt counter (the geale KO notwithstanding he wasnt actually tring to punch with him, it just kind of happened as geale threw a shot while golovkins step back-overhand move was already in motion.) It cost him against Jacobs, Chenko and Canelo. Big stylistic flaw
He could show opponents too much respect at times and let them get a little confidence back. Like in the 2nd Canelo fight where he had him with back on the ropes but inexplicably decided to not throw any punches.
Lack of decent opposition to show how good he really was. He looked amazing in his prime but would he have looked so good against top opposition?
Canelo was competitive in the second and able to outbox him in the third because he had a massive youth advantage. Like every other mammal, Golovkin lost speed as he aged. The same will happen to Canelo. To put it into perspective, even in the first fight Golovkin was already older than Groves/Degale/Saunders when they retired and when many others talk about hanging them up soon. As for Golovkin's weaknesses, he didn't really have any. He wasn't the fastest, but fast enough. He wasn't the biggest, but still big enough. I think the very aggressive style was for commercial reasons, to make more exciting fights and more money, and Sanchez had a lot to do with that.
Forget the ringside reporters their bias & agenda driven monologues have been on display since the old days.
