I find it hard to label one player as putting either team ahead of the other. Part of what's so great about the rivalry is that any one player can be the difference on any given day.
In the end, I think we might be hard-pressed to pick one player at the end of the tournament and say she was the difference for Team USA.
I was still somewhat new to hockey in the lead-up to Vancouver, so I didn't pay the kind of attention I do now. Did anyone on Team USA get the kind of hype that Kessel is getting now? It feels like they're building her to mythical status. I studied Comm, so I'm always interested in media coverage - I wonder if she wasn't injured during these lead-up games if the coverage would be the same. It feels like there's a big build-up BECAUSE a lot of these writers haven't seen her play (or not in awhile). Olympic coverage especially is notorious for picking storylines and narratives long before the actual games and just following them regardless of how they actually play out.
None of this is a knock on Kessel - clearly she's worth some level of hype and attention, but man is the "brother/sister" thing played out already and we're still two weeks out.
