This is a no brainer - Josi.

Fisher is too old
Johansen won't show up to play every game.
Subban loves being in spotlight, but might not reflect well as a captain. Though he is an awesome human.
Neal is a grade A wiener.

Josi is perfect age, awesome Dman and is already a leader.

I have to agree

My List:

C: Fisher or Nystrom, Gaustad
A: Pekka (yeah the goalie)
A: Josi or Subban

Doesn't the players choose the captain?

Semi biased opinion here but Josi is probably one of the most underrated dmen in the league

We'll see how well he does with PK instead of Weber.
Will change his game a bit I think. Not necessarily a bad change... but I think he'll need to be more defensive minded to make up for PK.

(Note: I loved PK on the Habs... but he did need a solid defensive defenseman to allow him to produce)
