I think that's as likely as anything.
Perhaps he is demoralized by the overall inept state of his team? He sure doesn't appear to be a leader. Could he be easily influenced and lack resiliency?
I think there are players- Rick Nash is a good example who are just not leaders and only reach their potential when they have strong leadership. Nash is great on national teams consistently among the best players on those teams.
If there is one thing a leader absolutely must have it's resiliency. If there is one thing the 2015-2016 CBJ have not shown on the ice it's resiliency. Apparently Torts rant about the lack of leadership on this roster rings true.
