This is a topic I have wanted to touch on for a while, so here we go.
The topic: The best performances by Penguins players that only spent one season in Pittsburgh before they were traded or exited via free agency.
Here we go.
Honorable mention: Michel Briere (1969-70 season). I put Briere as an honorable mention and not part of the ranking itself because he does not really fit the spirit of what I was looking for here. But he still deserves a mention. Yes, he only played one year for the Penguins, but that short career was the result of tragedy, not because of a contract or a trade.
