They moved them below Tech because of the WCHA autobid?
Not sure about Northeastern though? It appears they believe Northeastern has a better chance at making the tournament over Duluth despite Duluth's better PWR. (and despite the fact they believe UMD has a better chance to win the Automatic Qualifier: 12% vs 9% for Northeaster?)
Which means one can conclude Duluth will far further in the PWR than Northeastern will with possible upcoming losses (or climb higher with wins?) EDIT: Running through the USCHO PWR Predictor, it appears its because Duluth could lose two this weekend with the third place game. Since HE doesn't have a third place game, Northeastern at most would lose one game. Duluths wins one game (even the third place game) and likely in (and that's with Minnesota stealing an extra Big Ten spot by winning the autobid).....That's my uneducated hypothesis.
In Atlantic Hockey they have Robert Morris with a 33% chance vs Air Force with a 36% chance despite Robert Morris being #19 in PWR vs Air Force at #28. Robert Morris also won the regular season title in Atlantic Hockey. Not sure what to think of their math. Doesn't really pass the smell test to me.
