If it was today:
M Tkachuk - Matthews - J Hughes
Connor - Eichel - B Tkachuk
Keller - Miller - Robertson
Kreider - Larkin - Tuch
Boldy
Trocheck
Q Hughes - McAvoy
Werenski - Fox
Slavin - Faber
Sanderson - S Jones
Hellebuyck
Demko
Swayman
Obviously loaded, but I think one weakness is the number of one way forwards. The whole middle six here, plus J Hughes, is weak defensively, possibly with the exception of Jack Eichel. When Jack Eichel is your defensive stalwart then you might have trouble. Thankfully for the States, Matthews is great defensively and the coach can lean hard on the 4th line here, which is heavy, strong defensively, and crazy fast. Boldy and Trocheck can also come in for stronger two-way play.
After thinking it through, I might swap Miller and Keller for Trocheck and Boldy.
