In a tournament like this it is not uncommon for players to be displaced by others with more experience than them. RNH has already proven to be a capable C in the NHL, so it is not such a huge surprise that he is the #1 C on Team Canada. I'm just guessing here, but I don't think that a NHL coach will base their team's needs based on Steve Spott's line-up.

As for your question, I think Bnhershy said it well.
