In response to the idea of Kreider, which I've seen a few people mention, I don't want him on the team. I say that as a fan of the team he plays for.
I don't think he's a good fit for the construction of this team. If he's there, its in a bottom six role to begin with. What Kreider's best at is being a net front presence on the PP. He's probably the best at that in the game. But Pavelski isn't far behind at that, and he's pretty close to a lock for this team to begin with. Also, if Matt Tkachuk is on the team, he probably is in a top 9 role and on the PP. And if not, someone like Pacioretty is also another big forward that can play net front. We might not even have two traditional net-front guys for our PP set-up.
If Kreider isn't on the PP, what is he useful for? He's very fast. That'll be true for any situation he plays in, but he's not some ultra gritty forward. His defense is pretty lazy. He takes a lot of bad offensive zone penalties. He has barely played any PK in his career, only 3rd pair PK the last two years. He's driven hard with speed to the net a lot less after Markov tripped him, and he was accused of injuring Price. I think the reaction to that play, which wasn't even his fault, effected how he plays with hard drives with speed to the net. He's a very good forechecker, has great size and speed, and would be a great locker-room guy, but his actual usefulness to our bottom six doesn't seem clear to me.
The thing he's best at we already have covered, he's not a big PK'er, he's not a good defensive forward, and I'd be worried that playing 10 minutes per game on the fourth line he'd take a bad OZ penalty that loses us a game. He's also another left-shot LW that hasn't played much on the right side in his career.
