How long have you been watching hockey? I have seen plenty of offensive power house teams come to a screeching halt to a really good defense and goalie. Their plan isn't to play offensive fire wagon hockey against Canada. We see this same flawed argument often including this year at the WJC and guess exactly what was used to shut them down and close out the game... The USA has plenty of offensive from the forward area, they don't need to rack up gaudy point totals, though you probably have the best current goal scorer in the world, one of the greatest offensive wingers in the history of the game and a bunch of really productive players most of which actually have good defensive tendencies. Which means they are asking them to play a style that fits the group. Anyway I guess we will see.
This is going to be the best American team of my lifetime though, I can tell you that. Losing Eichel would be massive though, that would hurt unless Jack Hughes explodes this year which very well could happen.
