No bad losses, but their best wins are Dayton and Wake.

Remaining schedule:

@ Purdue
Illinois
@ Wisconsin
Maryland
Rutgers
@ Illinois
@ Indiana
Michigan
Purdue

I can see them losing @ Purdue, @ Wisconsin, Maryland, Purdue, and maybe Michigan. That would put them at 23-8/22-9, with their only decent wins being Dayton, Wake, and a sweep of Indiana. Their current conference standing is inflated due to the fact that almost all of those wins have been against the bottom half of the Big Ten (2x Nebraska, Ohio State, Rutgers, Iowa, Penn State).

In terms of them making the tourney...

It will probably depend on bid thieves/how soft the bubble is, but IMO they would definitely have to avoid a landmine in the first round of the conference tourney. I think they ultimately need 2 conference tourney wins to break the drought though...

...which I don't see happening. Northwestern: First Four OUT.
