Some posters seem to think Joey would "school him big time" which seems to me a somewhat ... excitable ... opinion to have. Outboxed by who, exactly? Everybody that he hasn't knocked out he's outlanded. You need power to earn Golovkin's respect, and it's clear Giardello doesn't have any. 1) Debatable 2) That's really not a typical GGG fight plan 3) He still ended up in hospital
I hope everybody took notice the relative ease that Carter managed to touch Giardello to the body. He barely set up his body work. Golovkin not only sets up his body shots by punching upstairs to raise the elbows, but he's pinpoint accurate and has fight-ending power. This is a montage of GGG's favourite body shot, the left hook to the liver. It's often the beginning of the end: This content is protected Again: Giardello would have to box out of his skin to beat Golovkin.
Giardello was considerably past his prime by the time of the Carter fight, his legs and reflexes were well dimmed compared to a few years earlier which was why Carter was able to catch up to him with greater ease. Carter was an excellent fighter at this point anyway and Giardello still beat him even if it was hard fought. Like it or not, Golovkin, excellent fighter though he is/was, spent most of his best years fighting guys not on Giardello's level nor the level of his best opponent's. Joey would represent a significant step up in class, although it's not unreasonable to give Golovkin a good chance. I'd consider it daft to be sure that Giardello wins with ease, pretty daft tbh, but you can't deny that Golovkin is the one with everything to prove in the event of them facing each other, not the other way around. Golovkin definitely has at least some tools to give Giardello grief in theory but the opposite is true also. I agree with @JohnThomas1, Giardello closeish but clear on his best day. I'd give Golovkin a keen shot in a series though and real time situ where Giardello is likely to rock up not in the best nick, the lazy fecker.
