MN keys in my humble opinion.
1. Don't dink around with the puck in the defensive zone. In other words, get the puck out of the zone whenever possible. Three of UMD's goals were a direct result of poor clearing by MN.
2. Get traffic in front of UND net/goalie - Score ugly & shoot often.
3. Remain calm. When MN starts running - especially in the d-zone - around it's all over for them.
