My thoughts on how Canada beats the USA:
1. Slow down the Tkachuks. The Marchand-Point-Jarvis line can really disrupt the flow for the Americans and are the ideal match-up line. Where they lack in size, they make up for in IQ, finesse and just being a step ahead. I think this is where Marchand becomes useful and draws in penalties so Canada's PP can cook.
2. You have to play a TON of Parayko when the Eichel line is out. He looked great against Sweden and you're going to need him if you want to shutdown Eichel's speed or the Tkachuks' size.
3. I think the Crosby line matches up really well against the Matthews line. They should be rolled out to go head-to-head with them.
