I mean, I suppose they are using it as a tool, but given the tendency to almost always favor 19-year olds and players in their D+1 (who aren't playing in these games) I don't think it will be very useful for choosing the U-20 team outside of maybe 4-5 guys per year. That is, unless they change the format to allow players on both sides that are over 18.
Looking at this team, only Martone, Misa, Spence, Schaefer and Ravensbergen/Ivankovic have realistic shots at a camp invite, let alone a roster spot. It is not like the old CHL-Russia series where the best of the CHL players, regardless of age and draft status, could be evaluated against international competition.
