It's hard to say w/o knowing who will stick in the NHL (Huberdeau, Hamilton, and Murray will likely be there...probably Gormley. Maybe Schiefele)...b/c those players wouldn't be available to play.
I think of the players who got drafted this year (leaving aside Murray)...Dumba, Reinhart, and Rielly should certainly make it. Ceci probably will as well.
Of the players who are eligible for the 2013 draft I would think MacKinnon should make it...and Shinkaruk and Monahan have an outside shot, too. There weren't that many great forwards from the CHL who were 2012 draft eligible...so that may make it a bit easier for 2013s to make the team.
Not a big name but defence man Frankie Corrado should have a good shot at it. Canucks drafted him 5th round in 2011 and has progressed extremely well. IIRC he was one of the runners up to hamilton for OHL best defenceman
I believe Sproul will keep developing at his quick pace and overtake Ceci. Rielly will be the 7th d-man acting as a PP specialist. I also think the World Juniors will be Pulock's coming out party which will make him shoot up the 2013 draft rankings.
