Wach is quite durable, but time has overtaken him, Itauma will crush him and stop him in the late rounds...
Disagree about Mezentsev. I am absolutely sure Dovbyschenko (who went full 6 rounds vs Itauma) would have KO'd that funny looking unathletic guy with extremely padded record. Dovbyschenko has better chin, power and skills than Mezhentsev
This is man vs. boy. People forget that Wach had a legit war with Whyte couple years ago who was top-5 at the time. I'm going with the Waching machine by 7th round KO.
