Imagine not having John Klingberg on here instead of Gostisbehere
I'd also try to fit Mark Stone, maybe by removing Guentzel/Wood, possibly Athanasiou.
Erik Gustafsson and Viktor Arvidsson are both options, especially Gustafsson could probably fill Krug's role to 95% for 1.2m cap hit. Dadonov is also an option, probably even ahead of Arvidsson. Gaudreau easily over Guentzel as well
Seriously consider Klingberg instead of Gostisbehere and I'd probably change that one. Had Krug on there because I'm loving the way he's playing in the Finals.
Took Guentzel over Gaudreau due to the other smaller guys on the team. Marchand, Gallagher, DeBrincat. I wasted a lot of time building this roster.
