You aren't wrong to say CK is a first line player because he's a top 60 winger in this league. On the other hand, Kreider as a first liner is similar to Stepan having been a top line center, because he'd have been a top 30 center. It's not mathematically wrong, but at the same time, no playoff bound team would likely consider it ideal to have Stepan as their top center. I see Kreider as more of a complimentary player on your top line. A nice player for sure, but never your go-to guy.
I've just seen enough from CK. His inconsistency and likely salary are just too much for me. Add to that his age, and I can see the back end of that new deal as horrific. He hasn't taken the next step like many of us hoped he would. He plays the PP, but not the PK which was always a disappointment to me since he has such an amazing skill set, but I guess he lacks the hockey IQ. He's a 50 point player who brings a unique skill set. I guess I believe he is a first liner, but I'm not crazy about paying him like one.
He had a good run here, and I enjoyed watching him play, but I think it's time to move on. It's more likely at the deadline, but I'm taking a first rounder plus a sweetener as soon as I can get it.
