Honestly, this is as good as gets historically for the U.S. I'd probably still give the edge to the 1996 World Cup of Hockey team due to the number of HOFers on that squad but top to bottom this team may have more depth. This would be a very difficult team to play againt. Every line has a speed, size, and skill.
