Minnesota is having a great season. No doubt about it that on paper, and from what I've seen, they are better than anyone in the NCHC.
Wisconsin is a solid team, but I would likely put them at parity with a UND or a SCSU
Michigan is pretty good, I would put them somewhere in the UND, SCSU, UNO, WMU mix
DU and Miami are sneaky...they can blow up on occassion and steal one with a hot goalie (Brittain) and a high powered top line.
Play the games- the proof will be in the pudding
