Ultimately, it will be whoever has the best leadership in the locker room, which none of us really know. However, my vote is for Kesler. I like what he does on the ice, and he plays with passion. He seems to be a good leader.
The Sedin's are obvious candidates as well, but I don't want them to be too distracted from actual scoring.
Sorry nuxfan, didn't see that you had this poll up. Didn't mean to steal your thunder, my bad. Since the other one is up on the feature poll and has some more momentum we'll keep it going there. I've updated the options on it to reflect some of your options.
