Not really. They are an older, more experienced team that plays hard-nosed hockey.
OK, they might tend to hold a lot.
In fairness, I like to watch refs "let 'em play". As long as they call it the same for both teams. That, sadly, does not seem to be the case. I felt UND was persecuted in the WHCA towards the end, and I am getting the same feeling now.
Nationals will (and always have) been different. We will have to see how the officiating stacks up.
