He's not as cocky as you think. They really play him up during promotions for his fights. I actually know his sister and nephews. They are good people.

As for his style yes he is a brawler. He is not refined as a boxer, but I don't think Povetkin nor Joshua could make him pay for that either. Everyone said Stiverne would finally expose him as well and yet he still won. Povetkin needed drugs to stay in the game like Fury. Klitschko is scared to throw a punch anymore against anyone. Like you said his fight with Fury was the worst fight I've ever seen and that's the truth. I think Klitschko landed like 52 punches for the WHOLE fight and I'm not exaggerating either. Boxing refs need a red and yellow card like the refs did in PRIDE Fighting in Japan. You got the red and you lost 10% of your purse to PRIDE.

Wilder has showed he has a chin and he has shown he is not going anywhere any time soon. He definitely has shown he has the power to put most HW's to sleep.
