I hope people watched this game with analytic eye. Slovakia, USA etc. has one goal = Huge intensity from the start and let's cause mayhem. You might look at ohh no they dominate, oh no.
But while game progresses and if they don't have that 4-0 lead, it's game over. Finns play exactly this same machine game, most of the teams get into full panic mode. Sweden for example shat their pants and froze because they had no idea what to do.
Momentum comes and goes, but they stay composed. Save your fingernails and relax, it might look bad at times but really there's nothing to worry about. Last regular time loss in major tournament is from 2019 so i guess people would learn with time.
