Skinner is actually pretty good at faceoffs just have him take more. You can get better at faceoffs easier than skating, IQ, etc... MacKinnon is a career 45.9% at the dot with 1 outlier season over 50%. He 41.9% the year he had 97 points and slightly better the year he had 99.
McDavid came in as a 41% faceoff player and got better every season so far peaking over 50% this year. I am not signing a guy just to win faceoffs. Complete waste of time and roster space
I think that is fair, you don't go out and get a specialist who can't take a regular shift. That is basically what we had in Eakin, a guy who isn't a NHL regular but good at faceoffs. I'd be with you that we don't want that.
But, your forward group needs someone who is at least above average at it. I think ideally you want one in your top 6 and one in your bottom 6 so you aren't shuffling out your 4th line on important offensive faceoffs.
