Yes it does. As a leader on the team he can set a precedent and demand a response. The coaches can too, it's not mutually exclusive. And if either group is waiting for the other to ask for the response it's a failure on both their parts.
This team continues to get pushed around I don't believe that would be the case if the leaders of the team demanded more of their teammates.
I tend to agree with this. It's the same thing with people not being accountable for their own mistakes. It becomes acceptable to not point out when someone else does something poorly because someone doesn't want anyone to point out what they themselves have done wrong.
