USA lacks intensity. Doesn't matter if they had more skill, playing this low-paced game will still rack upp losses in the WC.
I know it's easy to blame the player selections when you suck, but they could very well be down 5-0 if they had invited the players you mention.
If they had selected the right players, they wouldn't be down 5-0 cause they'd always have the puck against Team Europe. Big reason for a lot of their chances is the US has such a limited amount of playmakers and basically none on defense today. Constantly unable to make plays with the puck has let to odd man rushes
