Do you honestly think that fans discussing Horvat's suitableness for captaincy has any effect or sway with Aqulini, Benning, and Green? I don't.
Bo's performance on the ice and in front of the media makes him an ideal candidate, in my opinion. If he is given the C, it'll be because of those aspects of his overall body of work, and not because of where he fits in chronologically. In my humble opinion, a team captain represents the team on a whole and isn't always the team's best player. Is Shea Weber the best player on the Canadiens?
Bo's been the transitional leader from the older core to the newer one, and has never let up or lost focus. When Desjardins spoke about him as being a fourth line grinder, he took that on and persevered, never complaining to the press.
There will be a team captain this fall, by all accounts, and the probability of Bo being the captain is pretty high. I don't see that being a detraction or distraction to the team at all.
