What you have to consider too is that the Ref's are almost forced to call against certain schools, just to keep college hockey afloat. I mean if you think about it, well over half the schools in college hockey you would have never even heard of if it wasn't for their division I status.
Think about their recruiting. If you wanted to play college hockey, your first choices (outside hometown school) would likely be major universities like Minnesota, Michigan, Wisconsin, etc. Next on the list would be notable universities with major hockey programs (ie - Div I) such as North Dakota, Boston U, Maine, New Hampshire, etc. After a while you would get to the other universities with major hockey programs - but who maybe aren't household names (regardless of their success) like St Cloud St, Ferris St, Quinnipiac, Lake Superior, etc.
That doesn't leave much for recruiting if you're one of the latter schools. Hockey is a northern sport, and foreigners have little reason to play college hockey here rather then junior hockey back home. With slim pickings, it's no wonder you constantly see the NCAA's filled with BC, BU, CC, Maine, Mich, Minn, MSU, No Dakota, and a few lucky no-names.
My point is that if that Ref's call it fair, then every game between Minn & Mankato, Mich & MTU, BC & Merrimack would end up with a score like 8-1. I for one hate the Ref's, but I would hate more to see college hockey with 2 conferences - cuz the little schools cant compete. Schools like Mich Tech have a lot of history in college hockey, and I would hate to see them drop out of Div I. If that means a little clutch & grab, so be it. We will still leave Houghton with 4 points.
