The biggest problem with college hockey officiating -- especially in the WCHA -- is situational officiating.
Two or three years ago, Dean Blais was on the UND coaches' show complaining about the clutching and grabbing that's allowed to go on. That brought up the subject of the meeting that happens at the end of every season during which the coaches can talk to the league about officiating.
Blais said that when he asked for obstruction to be called more often, the WCHA officials responded by talking about when and where it would be called. In other words, the game isn't called by the rule book. It's left to the official to make a judgement about whether a penalty should be called in certain circumstances.
It's no wonder that WCHA officiating is so wildly inconsistent. When referees know that that they'll be allowed -- even encouraged -- to call some penalties and ignore others, then it's unrealistic to expect any sort of consistent standards.
This approach dominates college hockey officiating, and the NCAA knows it. In closing its open letter to the hockey community, the NCAA said (emphasis added):
The situational officiating approach needs to be be banished from college hockey. It'll be interesting to see how serious the NCAA is about doing this and whether it can force the WCHA to follow suit.
