TBN could solve this problem VERY EASILY.
1. Stop being children.
2. Every time they ask the Sabres for an interview on a topic, but are denied, write the story anyways, BUT also professionally point out that the Sabres were asked to comment on the story, but refused. Moreover, don't whine about it, embellish, project, and emote. Simply state it.
Point it out to the general public that they're shutting you out. Don't cry about it, just make it known that it's happening. Let public opinion form on it's own.
Then again, maybe the public is, for the most part, ok with it.
