I don't know if I should be happy that Phil found a line with natural chemistry in less than a dozen games, it could just be a product of having better players to work with. But the last 4 years we haven't once constructed a successful line (or if we did their impact was nullified with terrible usage). So yeah, he gets credit in my book.
Don't get me wrong, I have plenty of complaints about the coach, the GM, and the players. I have wanted to see Sam at center, Jack get a run with ROR, ROR not buried with terrible usage, Mitts & Tage spend some time in Roch, and Sobotka shot into the sun, etc. etc. etc. Many of the thoughts that get tossed around the echo chamber here are valid.
At the same time, I'm not going to knock the coach and gm for every bad aspect of the team, and then turn around and make an excuse for every good thing about the team. Far too many posters engage in this, but you have to be able to objectively recognize the good and the bad to make an intelligent decision.
