It's not so simple as averaging out numbers. Team context has to be taken into account. Subban to me, while being one of the best players in the league and our best player outside of Price, could very well be captain. I just think the RIGHT person for the job is Plekanec. He is just as much a leader, even though he isn't as effusive as PK. He's cool, collected and the guys also love him. He deserves this and 100% PK will be the next captain.
I also agree that Gallagher exudes captain material, but it would just seem weird. Best thing about our group is that so many of them are showing "captain material" properties. But when it comes down to it, you gotta go with the guy who has worked his but off even more than PK when you consider time with the team. I would be fine with PK or Pleks, but I think the latter deserves it and it's wrong when said that he's not a leader, considering he's our swiss knife of a forward. Gainey, Carbo...that sort of thing. Imagine him with capable wingers. Oh right, all you have to do is look back to the Kovy/AK days. Guy was an offensive gem.
Interesting table though. I can see your argument. Makes sense for many other teams, but I think they've built from ground zero up. That's not been our situation.
FTR, I think PK would be the ideal captain in terms of media, interviews, etc. I don't think he would crumble under the pressure. He would eat it up. Still think Pleks should get it. Considering we're going to deal him at some point, which saddens me, I'd like for him to go up in the pantheon of Habs captains. Deserves it AND I maintain he is a guy who "gets it". We've had lots of success and great moments prior to PK, and Pleky has been at the center of it. (Obviously we're striving for more in this new era.)
