Brassard did not sit out NHL or AHL games during a signed contract. Ask for a trade, fine. Agent makes a stink, fine. When you sit out games pouting it reaches a new level of entitlement in my opinion.
A new level of entitlement or an escalation of an already bad conflict? We only know what we're being told. Could be an entitled, spoiled brat trying to force his way out. Could be poor management and bad workplace relations or an agent offering some very bad advice to a young, dumb kid. Probably a combination of all tree.
We don't have the information we need to place the blame entirely on him.
