Ridiculous. Golovkin would be small for 168 lbs. never mind 175. Beterbiev would crush him with power and Bivol easily outboxes him. He's a significantly better version of GGG.
GGG has an ATG chin, and also a big punch, and Beterbiev isn't hard to hit. Other than maybe Bivol, GGG would be the most skillful opponent Beterbiev faced. If he gats caught early, GGG could well finish him off. It would be an upset, but not a massive one. My take on the probabilities: GGG by KO ......15 % GGG on points...15 % Artur by KO ....25 % Artur on points...45 %
GGG seems to only be courageous and take out bigger opponents in fantasy threads and imaginary sparring sessions. In reality though, he made a career calling out smaller opponents.
Who was smaller he actually called out? And I know your dumba$$ will try to say Floyd. He never called him out, he was simply asked about Floyd in an interview.
He may not have the size but he absolutely has the power. GGG hits harder than Bivol. Now i think Beterbiev stops GGG but the idea that GGG couldn't hurt him isn't true.
Increase Golovkin's size by 2% and he beats Beterbiev. Beterbiev's power won't be effective on Golovkin's iron chin.
