U-29 (players likely to be at a high level if NHL goes to the next Olympics) forwards:
Skinner-McDavid-Marner
Hall-MacKinnon-Seguin
Huberdeau-Point-Scheifele
Duchene-Tavares-Stone
Dubois-Barzal-Stamkos
Drouin-Domi-O’Rielly
Monahan-Horvat-Reinhart
Marchessault-Johansen-Gallagher
Schenn/Schwartz/Kadri
(Just by going down the NHL stats, I could make a whole ‘nother forward roster before more than 6 Americans + Matthews and Hughes were slotted in)
vs.
Gaudreau-Matthews-Keller
Tkachuk-Eichel-Boeser
Connor-Hughes*-Palmieri
Tkachuk*-Larkin-Tuch
Trocheck/Zucker/Kreider
*Dependent on projected potential
U-29 “top pairing” blueliners:
Canada: Chabot, Rielly, Pietrangelo, Hamilton, Girard, Morrissey, Ekblad, Ellis, Brodie, Dumba, Pulock? Matheson? Parayko? Nurse? Severson? Barrie?
+ Doughty, multiple Norris winner, only a year older
USA: McAvoy, Slavin, Jones, Carlson, Werenski, Trouba, Dumoulin, Fowler? Leddy? Skjei? Ghostisbehere?
America seems to have an edge in goalies for now, but it’s the most unpredictable:
Canada: Murray, Jones, Allen
USA: Gibson, Hellebuyck
The US should probably have to visibly surpass Russia, Sweden, and Finland before it gets compared to Canada. That said, I fully expect them to be the dominant hockey power within two decades.
