Kreider is very unique to the point where his skillset is impossible to find in another player. Very few have that size and speed.
The thing is, we don't need a replica or anything like that. We do need someone who can skate well and have size.
His biggest downside is his puck skills. I'll gladly take someone not as fast but is a better passer and can be a net front. Those are hard to find too. Might need to be drafted. Big wingers usually go in the top 10, unless you get lucky and find one later.
It's a long shot, but someone like Barron could be that kind of player. He has puck skills and size, just not the speed of a Kreider. Let's see him in 18 months or so and where he is. Might be able to make a jump from NCAA to the NHL, but most likely some AHL time is needed, maybe even a full season. Just don't rush him.
