Nothing to do with the outcome. Harvard lost a much more "tough to take" game against BU, but BU played the game clean and while the loss was gut wrenching, I thought BU played a clean game.
I have seen Quinnipiac play once this season (n=1) so take what I say with a grain of salt, but I thought Quinny displayed as much stick work, interference (Harvard players entering the zone), and unnecessary hitting as I have seen this year....and they are too talented a team to do that.
I like a clean, crisp game and hockey is at its best to watch when the refs call the game that way.
The game is over now, but I would encourage you to re-watch the game and focus less on the puck and more on the sticks, the interference as Harvard entered the zone (should have been called way more), the hitting up high, etc.
The call on Donato for boarding was spot on. You can't hit a guy with his back turned to the wall like that, regardless of how "hard" hit was. That type of penalty is generally not in his nature and I am sure he was frustrated given where the game was at that point. But that's no excuse. And from what I heard, Donato gave his son a very stern talking to when he made his way back to the bench.
Quinnipiac is a great team - the class of the ECAC. A much more complete team than Harvard (Harvard's defense is not good enough this year).
