Some folks are never going to be happy with anything short of prime aged Shea Weber or Jarome Iginla as captain. Some folks want big, tough, willing to hit and fight, great at both ends, able to pile up points, able to deal with the media, basically able to do everything. Simply put, some folks want a unicorn.
Quinn is an excellent choice, he was the right choice. He shows up, takes responsibility, leads by example, owns his play, and he's respected. Captains don't have to be able to fight, they need to be able to lead. They need to be able to command the respect of the room, to be there for each player, to be able to connect with each player. They need to be able to handle the Canadian media in a professional manner. Quinn can do all of this.
