Completely agree with people about keeping this line together. These three are a treat to watch offensively, and if kept together for a full season, could each reach or top 60 points, I think.
They aren't great defensively, besides Zibanejad, who I think is pretty underrated defensively, but so what? Deploy them as the first line offensively. Kreider's speed, drives to the net and ability to hunt in front of the net adds one type of game, Zibanejad's more defensively responsible game helps out the other two and he differentiates from the other two in that he's almost always looking for space to set up for a one timer. Buchnevich's desire to hold onto the puck, create space for himself and then find teammates with very good all-around passing ability and pass-first mentality can set up these two pretty well. And they are all pretty dynamic. Its not like watching Stepan, lets say, who's good, but is a boring offensive player.
