First of all, CC is much better than a lower half team, they must play inconsistently to be where they are. Can guarantee that noone wants to get CC in the playoffs. And, if they win down the stretch, they'll be waiting with home ice in the regional.
The Sioux are not playing poorly, but they are in a major struggle to put the puck in the net, unlike earlier in the year. I don't believe there has been a game this year that the money line had more good chances than last night.
At this point, if the Sioux can't sweep both Mankato and MTU, I'll be pessimistic about the NCAA's. They also need a win against the (currently) best team in the WCHA, Duluth, to spring them into the playoffs.
