At no point do I say that Max is a "bad player" -- and I have acknowledged that he is good for 30+ goals. The notion that you think I think he's a "terrible player" is an inference that you are making. What precipitated this discussion is my reference to the fact that Max has a habit of disappearing when it counts. Clutch, he ain't. Regarding the power play, 5 goals over a hot weekend has catapulted the Habs into the top 10 power play overall in the NHL. However, the PP has been problematic and in the tank for the last few seasons and a half. And Max is no centerpiece on the PP--historically, it has been PK, then Weber--and now, Drouin. For the most part Max was playing off the RW wall almost exclusively whenever he was on the PP, not in the slot or in the front of the net. That is where Gally goes. The current success with the PP sees Chucky playing off the RW wall right now in Max's place and I would suggest that has been a difference maker with the current success on the PP. Historically, Max's PP stats has been pretty mediocre for the amount of ice time he has gotten on the PP--and during that time the Habs have had a mediocre PP.
To suggest that his value is cemented by whatever "expected return" he may get in a trade is a false equivalency and entirely speculative--it's like saying, "My goat is worth four ducks. See!" ... and you have yet to go to market to make the transaction.
