No doubt.
If the WCHA called the games like the Intl, it would really separate the league, which is probably what the league doesn't want. The UAA, MTU, MSUM, etc of the league would really be lower-tiered when compared to the UND, UW, DU, UMN, etc.
The talent from those teams would be allowed to actually skate instead of being tackled for the game, which would really allow them to shine offensively.
