I'm surprised that people (well at least some) hate the hooking call that much, I can see being eh about it but it seemed like a rulebook hook to me. Refs probably more inclined to call it because Kazakhstan would've gotten a scoring chance out of it. Though if it was actually called holding that's weird.
In any case it's not like one call is a total lock to turn a game around, that Kazakh forward still had to take another totally boneheaded boarding penalty for that. That's totally self-inflicted and of course something you basically never see from a veteran, but that's Junior for you. And Germany capitalising of course.
Germany definetly got lucky and tough break for Kazakhstan to outplay the on-paper favourites going in but lose because of penalties and PKing. One of the worst ways to lose for sure.
