I don't really see any potential candidates for captaincy on this roster after Z. Unless ofcourse Kronwall ends up sticking around longer than Z does.
Really? Between the roster and the pipeline, we have, I think, a number of potential candidates. Abdelkader, Glendening, Nyquist, Sheahan, Helm, DeKeyser, Larkin, Nastasiuk...I've no doubt that by the time Z's career is done, there will be an obvious successor.
