I'm really glad that captaincy isn't a popularity contest. Sometimes I wish Bergevin would name Moen as a captain just to laugh at the ensuing ****storm.
On-Topic: Don't let my avatar fool you, I'm not a particularly ardent supporter of Gorges for captain. I'd be totally down if it happened - Captain Gorges has a really nice ring to it. He's a vocal player in the dressing room, isn't particularly gifted but compensates by his exemplary attitude and his defensive abilities are underrated by most. Gorges wearing the 'C' would definitely not look out of place. The 'A' is fine and should logically stay though.
The good thing about this team is that there are plenty of players who could be named captain and deservedly so. Pick one out of Plekanec, Markov, Galchenyuk, Subban, Prust, Gorges, Desharnais

and it will be a good choice.
