Most of the penalties in the playoffs were not of the stupid kind. The only dumb penalties that were taken in the playoffs that I recall were Witt's retalitory slash that lead to a 5 on 3 PP (granted a penalty should have been called for the blatant trip on him), Hartnell's trip will line changing, and maybe Erat's roughing (but I will give Erat a pass on that one because you have to stand up for your teammates...the pkers let Erat down in that instance.)
Kariya as the 'A' if anyone of the above gets injured or a permanent 'A' if he was to sign a contract extension before next season.
Hartnell is the least deserving of being an alternate, he still has a lot of maturing to do.
I don't put stock of who is going to be here when, New Jersey made Niedermeyer Captain his last year in New Jersey.
A-Walker, Timonen, Sullivan
I don't see Greg Johnson returning to the team (possibly even retiring), and Scott Walker is questionable as well, IMO. If neither of those guys return, I'd give the captain's "C" to Kimmo Timonen, who been with the team from the beginning and is the backbone of the team's defense. If Walker's still here, he'll keep his "A", but he'll likely be injured a lot. If Johnson and Walker are both gone, I'd see Timonen as captain, and Sullivan and Kariya as alternates.
