I've been one of the "haters" this playoffs. But I'm not sure I would look to dump Nash just yet.
It can take even elite players a while to figure out how to play their game and/or adjust their game for the playoffs. It really does become a different game, and there can be a bit of a learning curve. This is a big part of why I'm willing to (sort of) overlook Nash's playoff struggles. He stepped up his defensive game these playoffs, and now he's got to put together the offense with it.
By way of example, here is a bit of trivia (for "haters" and "defenders" of Nash alike):
Which elite player (not named Hossa), who these boards would have absolutely salivated at the prospect of having on NYR the past few seasons, struggled just as badly as Nash in his first 42 career games played in the playoffs while playing on one of this league's elite teams? [And this player has, since those first 42 games, put up nearly a point per game pace in the playoffs, scored goals at a rate 5 times what he was during those 42 games, oh and is pretty damn good defensively as well.] See below for stats comparisons:
Nash in the POs to this point in his career over 3 playoffs:
41 GP, 5 goals, 13 assists, 18 points. 0.12 goals per game. 0.439 points per game.
[Answer in first 42 PO games over 4 playoffs]:
42 GP, 3 goals, 12 assists, 15 points. 0.07 goals per game. 0.357 points per game.
[Answer in next 103 PO games over 8 playoffs]:
103 GP, 36 goals, 57 assists, 93 points. 0.35 goals per game, 0.903 points per game.
I'm willing to give him another shot. But he has run out of second chances. If he can't figure out how to score in the playoffs soon, then you just have to cut your losses. I don't know how you do it with the NMCs and NTCs. But you just can't afford to be paying a forward $7.8 million who can't score goals in the playoffs. Just can't do it.
