I think that's the real advantage with Guentzel. That you can rest pretty easy on the assumption that he's going to be adaptable and basically bring plug 'n play chemistry with whichever Top Center you want to pair him with. He's that sort of complementary "glue" player. Buchnevich is a bit more of a dominating player individually...which can be a good thing, or it can be a detriment if it doesn't end up being a natural chemistry fit with whoever you want him playing with. There's more "integration risk" with Buchnevich i think. As one of those wingers who plays a bit more like a traditional "center" in terms of controlling the puck and flow of play, where things run through him, compared to Guentzel who is better at doing the spadework but letting the play flow through that #1C.
