Yes he dropped off, from say 100% vs. Arreola to maye 60-70% of his peak abilities. Thing is those 60% may still be too much for lesser guys like Pulev or Helenius (both with a terribly low workrate). Not so sure vs. Povetkin (good workrate) or Haye (good counter punching).
:rofl Yeah sure, he would KO Vitali with his safety first style, sureatsch Couldnt stop Wach and he is going to stop Vitali, plus Vitali is even bigger so he would not be able to go octopus on him or lean on him to tyre him. Prime Vitali TKOs Wlad!
I love that Charr knockdown. A slap on the temple and down he goes like a fat kid that was slapped for having a big mouth.
The K2 brothers have extremely thin skin, they're both tomato cans in that aspect. Wlad would cut up Vitali rather easily. Vitali doesn't punch as hard so Wlad would get fight ending cuts probably later than Vitali gets them. It would be tko6 all over again. Also it's not unlikely Wach got a better chin than Vitali, also he's bigger than Vitali.
