Although not teammate related but team player/management related.
Dale Hawerchuk had some beef with the new management regime, when John Ferguson was fired and they hired Mike Smith as the new GM. The atmosphere changed immediately and Hawerchuk has spoken out loud that he and Smith never got along. Wasn't that ironic that the 89-90 season was Hawerchuk's lowest point total up to that point and he was soon shipped to Buffalo for Housley and a pick.
Then in an ironic twist of fate, Housley was in need of a new contract after the 92/93 season and him and Smith battled words back and forth. Apparently, they got into an argument at the Jets year end banquet and the choice was obvious that Housley wasn't coming back.
Then the Selanne debacle in the middle of the 95-96 season..
Things weren't the same since when John Ferguson was fired
