What makes this year very different is the fact that Head Coach Brent Sutter and Team Canada invited only 25 players, whereas in the past they have invited as many as 40. The fact that the roster only has to get down to 22, means that the 3 Winterhawks are virtual locks to make the team.
Petan, Pouliot and Leier all played extremely well in the Subway Super Series, where they played for Team Canada Coach Sutter. This had to help them make the 25 man camp. Because Edmonton's Griffin Reinhart was invited and has to serve a 3 game suspension and they only invited 8 D-men to the camp, Pouliot has the best chance to make the team of the 3. He was also a late cut from last year's camp, meaning that they will probably give him his shot this year, similar to what Ty Rattie went through.
Portland plays Seattle December 13th and 14th, so all 3 will be out for that game and should they make the team, 6 games December 27th-January 4th. This includes the last 2 games of the season at home vs. B.C. Division leading Kelowna.
