I've seen a couple of Team Canada's game - He's been insignifcant, you wouldn't notice him on the ice if he wasn't as tall as he is.
Usually that's a good thing for a defenseman though, and I'm not sure what role Myers is supposed to play on this team, but I haven't seen him rush the puck, or do anything on offense so far.
So again, take your pick - He's been either brilliant, or invisible.
