I disagree there. In the All Star game, there is no hitting. These games were hard hitting.
I think the biggest problem US players have is getting used to the 'big ice' in international hockey. I'd love to see the NHL expand the rink size. It's a better game, IMHO. But I know that ain't going to happen. They would lose too many prime seats doing that.
It sounds like an odd way to run a league, but the NHL did it for years when they had some rinks with smaller ice surfaces (the Boston Garden and the Aud in Buffalo were two of the smallest).
