I know they probably won't but I would consider putting the Tkachuk brothers around Larkin and running that as an annoying as hell checking/scoring line. They can be your defensive matchup line against the other teams top lines, freeing your matchups for Eichel and Matthews as well.
I also believe in teammates when it is possible. This makes some of the bubble guys interesting. Do Miller and Boeser as a tandem make sense? DeBrincat and Kane? This is short tournament, I always agreed with this thought process from Yzerman when it came to Canada, he used teammates for chemistry and roles at times to tiebreak we will have to see if that is a part of the thought process.
Connor - Matthews - Wheeler
DeBrincat - Eichel - Kane
Tkachuk - Larkin - Tkachuk
Gaudreau - Miller - Boeser
Hughes Trocheck
I have hard time seeing them leave Pavelski though and could see him in, if Guentzel bounces back he pushes hard, he is my biggest omission. But what I like about this forward setup is you have natural linemates from their teams, you can switch the first two sets of wingers. I doubt Johnny Hockey plays this low, ultimately as a USA fan, finally I feel awful about some of the guys being left off and some of the roles, which is a really good sign. Maybe you throw out DeBrincat and put Gaudreau there, but this is just where I would be on it right now.
Love our D: The name not being said a lot that you have to wonder in terms of old guard is Suter, he wouldn't be on my team right now.
Werenski - Jones
Slavin - McAvoy
McDonagh - Carlson
Hughes
On current form Petry might be an interesting 8, again I can see this being Suter. This spot is hard, it will probably be clearer due to form closer to the tournament. Big thing to remember with Hughes not on a pair is that you get to dress 13 forwards and 7 d-man in Olympic hockey, so he still runs PP1. Also you can work in shifts, I just wouldn't put him with Carlson at even strength unless chasing the lead.
Gibson
Hellebuyck
Different feelings on third goalie. Bishop hasn't been healthy in a while and isn't reliably healthy so that is a gamble to me, I also admittedly have never been his biggest fan. Then you start looking at young guys. As excited as I am for 2022, I really believe 2026 we should be even better again. It is the trajectory of our current program. So with that in mind, my third netminder would be Spencer Knight. I would let him experience this as the third netminder, he is the next one for me, start grooming him.
