I completely understand the frustration, but it seems that every conference in country has an officiating problem--at least the fans constantly complain about it. If that is true (and I admit I can't prove it), then improving matters would have required some major changes, not just by NCHC but throughout college hockey. That is a complicated matter and probably expensive. Necessary, perhaps, but far more complicated than just giving some refs the boot.
At least that's the way it looks to me. And I'm never wrong, you know.
