You nailed it.  Crosby is low-key, humble, and has the team-first ethos in his bones.  Raised right.  PK is a grand personality and no doubt a delightful guy, but he was out-foxed by the Kid -- the bad-breath comment was just dumb, and I would not be surprised if the rumour is true that PK's teammates were mightily peeved at him for poking the bear.
