I don't think it's assuming anything, which is kind of the point. Trying to predict the standings using probability equations in a league where the teams are so close just doesn't work too well. Whatever the odds say, I will bet the farm that they don't match how the standings will finally look.
As for your statement that MN and MSU aren't capable of taking games, well...they each are at .500 right now, so they can obviously win. And I agree, MSU will almost certainly not get home ice, and UAA will almost certainly finish in 9th. But that doesn't mean they are easy teams to sweep. Just ask DU.
My point is, if any team takes a night off in this league, they will probably get beat (unless they are playing Tech

) That's a hard thing to predict based on numbers.
And I agree, if the Gophers get swept this weekend, stick a fork in them. This team NEEDS at the very least 2 pts against UND, and really I think 3pts is kind of the minimum in order to gain even a little bit of ground in the standings.
