Ultimately, the person this likely screws over is Max Domi, who likely would have made it to represent Arizona as a forward otherwise.
What's the Pacific team likely to look like?
The goalies will almost certainly be Jones & Quick.
The defence is likely Ekman-Larsson, Doughty, and Burns.
On forward, you have Scott guaranteed. Gaudreau is Mr 3-on-3, so you know he'll be there. Hall is putting up points in Stinktown.
Anaheim needs a representative, which is probably Perry by default.
For Vancouver, the Sedins are carrying them this year, so it has to be one of them, but I can't see them both going.
That leaves one extra spot. Pavelski is a point a game player who has never been to the ASG, so you have to think it's his spot.
