I thought I heard something about Drew Doughty playing? That would be huge.
If Doughty isn't on the official list announced by HC - as it appears right now that he isn't despite that one report - the one who made that up should fire himself from his twitter account. If you don't know something for sure, don't tweet it as if it's a clear thing.
On topic, I hope we could get Subban, who would have more or less the same impact. I think he would very likely go because of his past record:
2011 - eliminated in the 1st round. Was invited but declined due to "bumps and bruises". Also needs to be said that he wasn't THAT good yet.
2012 - available, he agreed to go and was on the team, but injured himself in pre-tournament game
2013 - Montreal eliminated in the 1st round, Subban flew immediately FOR ONE GAME (the group stage of the tournament was already over, and he still decided to go)
2014 - not available, Montreal advanced to the 3rd round
2015 - not available, Montreal advanced to the 2nd round
2016 - available, wanted to go, but was injured
I have no doubts that he will go if he's asked. The same goes for McDavid.
