I'm a Northern grad and fan, and I agree with you--the polls, PWR, and bracketology don't make sense sometimes. NMU has had kind of an up and down season, but have sort of kept themselves in the hunt because of SOS. They still have a tough schedule ahead of them: 7 road games and only 4 home games. I suspect LSSU has a competitive schedule as well.
I don't think there is that much difference between NMU and LSSU or the rest of the CCHA and only the next couple of months of regular season and playoff games will settle it all. Right now I don't pay much attention to any of the polls, rankings, or bracketologies. Wait until March. I try to just sit back and enjoy the hockey.
LSSU follows NMU playing MSU this weekend. Northern tied 5-5 (SOL) and lost 2-1 to MSU. I was at the Saturday game and it could have gone either way, but NMU got into penalty trouble in the third period and Sparty held on for the win. I suspect the Lakers will have a tough series with Sparty. In the Pick-em thread I chose a split, with LSSU getting their usual Saturday night victory.
LSSU @ NMU 2/24-25.
Edit: Just as an after thought, I thinks it's best for LSSU and NMU to fly under the radar for the time being rather than having a high ranking target on the back of their jersey.
