The big picture:
Minnesota is the only team guaranteed an at-large berth at this point. Pe. State, Ohio State and Wisconsin are bubble teams, but the Badgers are on the outside looking in, and PSU and OSU are at 13th and 14th respectively. With the WCHA and AHA guaranteeing that only the top 14 are in, and who-knows making that number even smaller, it's basically must-win for all of them. Whatever hope there was for up to 4 B1G teams making the NCAAs is pretty well dead.
In other words: PSU or OSU might get lucky with a one-and-done performance, but I wouldn't count on it. I'd expect the tournament champ and the Gophers (and that's it) to make the field at this point.
Predictions? 50% chance that the Gophers take it. They're clearly the strongest team left. 3% chance Michigan rides their high from last weekend to the title. 15% chances for each of Ohio State and Penn State, who are both slightly better than the Badgers at the moment, but will have to play an extra game to get to the promised land. 17% chance for the Badgers, who are playing awful, and maybe won't stand much of a chance to get past Penn State, but still have a fairly high ceiling and one fewer game to play to get there.
