This is going to be one of the more interesting camps in a while, I think.
You have your givens up front in Zibanejad, Strome, Kakko, Lafreniere, Buchnevich, Panarin, Kreider, Chytil, Lemieux, and Howden
and Trouba, Fox, DeAngelo, and Lindgren on defense.
That leaves at least two forward spots and two defense spots in the starting lineup wide open (IMO) for contention. I don't think it's a given Gauthier makes it. Blackwell, Rooney, Barron, and Gettinger are all stiff competition for bottom 6 spots. I think lots will be shocked by how many NHL games Blackwell gets. Rooney is going to be needed to kill penalties. I'm not sold Gauthier is a consistent starter from day 1.
The left side of the defense is going to be really interesting to follow. Lindgren is the only one with a definite spot on the left side. Smith is going to play because of the experience and grit factor. That leaves Johnson, Miller, Reunanen, Hajek, Robertson, Crawley and Bitteto for one spot. Crawley and Hajek are pretty safely AHL'ers, but honestly anyone else on this list has the capability to grab the brass ring and force themselves into the picture. Johnson has no business seeing NHL games as long as one of Reunanen, Miller, or Robertson can prove themselves competent, but it's going to be the same old song and dance. Bitteto is your 7th defenseman regardless due to expansion rules, I think.
