He's good, hopefully he gets a shot in a role that realistically mirrors his position on bigger editions of Canada.
Given the teams currently out of the playoffs, here is what I would like to see. This assumed that everyone says yes and ignores players in the playoffs. I want the team to be solid, but my main goal is to get young players in positions to get valuable international experience.
Benn Seguin Johansen
Hall Couture Eberle
O'Reilly Duchene Simmonds
Skinner Nugent Henrique
Couturier
Vlasic Barrie
Campbell Ekblad
Methot Brodie
Rielly
Bernier
Hammond
First line features Canada's best left wing, one of Canada's best centres (who has never played for Canada in an IIHF tournament) and a big, two way goal scorer in Johansen. I can see Johansen in that role for Canada at more significant tournaments in the future. This line has everything. Second line has some familiarity wth Hall and Eberle (two of Canada's best wingers, though they don't always play together in Edmonton) and a good two way centre in Couture, who might figure in Canada's plans for the future on the wing. Third line is balanced with speed and creativity from Duchene, elite defence from his occasional linemate O'Reilly, and grit from Simmonds. Fourth line gives an offensive boost with Skinner (generally quite good internationally) while Nugent Hopkins is developing into a solid defensive centre and Henrique is solid all around. Couturier is there to provide some defensive cover and kill penalties. Strongly considered Turris here.
Defence isn't as good, but that's the reality of this tournament. Vlasic is an elite defensive defenceman, and Barrie is a very good emerging offensive defenceman. Campbell and Ekblad are paired in Florida. Campbell is still an elite skater and provides a bit of experience, while Ekblad (despite seemingly slowing down) looks like Canada's best young defenceman. His size helps too. Methot brings size and experience, while Brodie is a good all around young defenceman. Rielly looks really good since Toronto's coaching chance and could slot in anywhere.
Bernier is a good goaltender, and Hammond has been ok thus far. Not many goaltending choices.
I didn't bother with veterans like Thornton and Spezza, or with Giroux. Some young players like Monahan, Stone and Ceci wouldn't be too bad.
