I'm sure I'm missing many candidates but if we're assembling a super team, these are many of the names that come to mind. From there, the risk is just choosing the most talented and not have them gel. I think you had the ability to choose from all these players, you get a talented coaching/management group together, come up with a vision for how the team is going to play and then pick based on fit.

GOALTENDERS:

Rask
A quick attempt:
Ovechkin - Crosby - Kane
As all 3 guys like to carry the puck, this line would work better if they focused on give and goes and cycling between Crosby and Kane and Ovechkin functioning as a Hull-like shooting threat, with the added benefit of being able to attack of the rush.
Tavares - Malkin - Tarasenko
Wasn't sure about this line. Tavares is at his best at center but feels too good to leave off an offensive line. Provides a playmaker for Malkin to work with, while Tarasenko provides a deadly shooting threat and is dangerous off the rush.
Benn - Kopitar - Seguin
Proven chemistry between Benn and Seguin, anchored by Kopitar who can fill the Getzlaf/Thornton two way role better than either Canadian.
O'reilly - Toews - Bergeron
Not the most talented line the world could ice here, but one I've always wanted to see. Three of the best defensive forwards in the game right now all playing together to suffocate whatever matchup they were up against. All have enough talent not to look out of place amongst the world's top players. O'Reilly provides an extra left handed face-off man, Bergeron provides a right handed face-off man.
Extras: Mcdavid, Pavelski
Mcdavid because his talent is too much to ignore. If one of the other centers is hurt or not playing well he can take over. Pavelski brought as an extra in case we need a bit more scoring to sub into this line. There are 6-10 guys who could be subbed into this lineup from around the world with whom the team would easily be as good or better though.
Keith - Doughty
Proven chemistry, if healthy Keith is still a top defenseman in the world.
Hedman - Karlsson
One of the world's best LHD with the world's best RHD and puck mover.
Josi - Weber
Proven chemistry.
OEL, Suter, Mcdonagh, Pietrangelo, Subban all good choices for this team. Potentially over some of the groups above. If we're looking a couple years in the future, could sub in OEL/Pietrangelo over Keith and Weber as they age.
