I think he has a legit argument. Russia indeed has a better crop of forwards, but their superiority ends there.
As for defensive and goalie depth, if we were only to take players 24 and under, this is how the two countries stack up:
U.S.:
*Leopold
*Orpik
Suter
Komisarek
Gleason
Whitney
*Jillson
*Tanabe
Stuart
Hainsey
Ballard
*Hale
*Martin
*Liles
Welch
Thelen
Russia:
*Kalinin
Tjutin
Kolstov
Grebeshkov
Knyazev
*Volchenkov
Babchuk
Kadeykin
Kondratiev
Lyamin
*Already in the NHL full-time
There's a notable difference in quantity at first glance, but also in quality, IMO. Not to mention you see many of the U.S. defensemen have already found full-time jobs in the NHL, while only two notable Russian defensemen have. Guys like Komisarek, Tjutin, Kondratiev, Hainsey, Gleason, Babchuk, and Grebeshkov have also played some games, but none have yet stuck for a full season. And although Russia has the blue chip forwards that the U.S. doesn't have, the U.S. has the blue chip defensemen that Russia doesn't in Suter, Komisarek, and Whitney who are all top 10 picks (this is if you wanna leave Leopold out of the discussion). Not to mention they seem to churn out at least one top defenseman in each draft.
