At the end of the day its on the players to perform. The team that Drury put together this year, on paper, should have easily made the playoffs. It's not Drury's fault that Mika, Kreider, Fox threw a pity party for 80% of the year and packed it in. All those guys cared about were exterior factors instead of what they get paid millions of dollars to do, play the game.
I don't think Drury is a great GM by any means, but to place the sole blame on him is ridiculous. Nothing is ever good enough for Mika and Kreider, there is always finger pointing. Not once have they ever said "I need to be better".
