I could actually see it happening.

Northwestern W
at Penn State W
Minnesota L

Even so, 7-2 might not be enough to get Iowa into the tournament, unless it involves wins at Wisconsin/vs. Minnesota, and at Indiana.
They'll beat Minnesota at home and could beat Wisconsin on the road. 7-2 looks very possible with that schedule.
