I know you are one of many who have defended Nash in this manner. I bolded the point in your argument because they serve as a good summary of
all the points of the opponents in this thread.
I think your problem is that although the points you made are correct, your are wrong none the less.
Your argument is
NOT non-sequitur. In a vacuum, your conclusion follows its premise.
Your Premise: Nash is engaged, he's hitting, and he's skating
Your Conclusion: Rick Nash is not the worst player on the team
Although this may not be the strongest argument, I agree with your conclusion, Rick Nash is not the worst player on the team.
Here is where you are wrong. I repeat. This is not just against you, but as I said your post was a good summary of every defender of Nash's play in terms of this thread.
Your fallacy falls into the classification of
ignoratio elenchi. To a logician your conclusion would be called an irrelevant conclusion. In everyday terms, an irrelevant conclusion is a more sophisticated phrase for...
missing the point
As many of those who are dissapointed with Rick Nash have said, he is first and for most here to
score goals. He is not. We are worried that if he doesn't, we will not be able to advance. We are also frustrated, that yet another "missing piece" is not contributing where we need him. We are concerned that the key players on this team are in a narrow prime window, and if we don't hit the mark, we will need another rebuild.
This is where Rick Nash is needed to score goals.
Let's say someone was crapping on Carcillo. (Yes! Some people actually said in other threads that they are still concerned with Carcillio playing, and we should consider Miller of Fast for the second round

)
Let's also forget the fact that he has two key goals.
I would agree with a defender of Carcillio's play who said Carcillo is engaged, hitting, and skating, but we are talking about Rick Nash. This team's supposed go to goal scorer, in a thread about his lack of goal scoring, and there are still people saying that this isn't a problem?
I feel like Clark Griswald in Christmas Vacation during his famous holiday rant.
