I think that politically they will want at minimum 4 from the "Q"....
Esposito will need to make it as a starter at centre--I cannot see them just keeping him as a "floater" =13th guy for the "experience"...this is usually a 19 year old's tournament and Canada is actually very young this time out...
Given my assessment of the "politically correct" minimum---I see Burdon as a lock (if he is healthy) ,Letang as either 6th or 7th D-man,and Latendresse as a lock--meaning Brassard and Esposito battle it out for that last "Q" spot unless Ellis gets a goalie spot...IF Ellis gets a goalie spot --they may keep Esposito as a 13th for the experience but only if Brassard doesn't make it...remember he and Latendresse play together and have chemistry and Brassard is lighting quick--he may be slightly slower than Cogliano in straight line speed but he is more agile laterally and is a centre who has better vision and passing ability than Cogliano ...
Another factor is that they will want good PK guys=Bertram and Comeau ...there is flexibility in that Bolland can play all 3 forward positions...
Looking at everything from political considerations to age mix,specialy roles,checking line etc.. I see it this way:
Forwards:
Pouliot Brassard Latendresse
Bolland Toews Blunden
Setoguchi Chipchura Bertram
Comeau Little Boyd
13th =O'Marra
There is flexibility and depth ...only if Esposito demonstrates that at his young age he can start--he'd have to beat Brassard or Little out of a spot--is it worth the risk
to keep him on the team...
Defense:
Barker Russell
Burdon Parent
Staal Letang
* Stephenson =7th Dman--or he is the 6th and Letang is the 7th
Goal:
Price
Pogge (a hunch)...
