If they go 7-8 the rest of the way they’re going to finish 10-10 in clearly the best conference in the country.
They already have quality wins.
St Louis
Iowa
Michigan state
Ohio state
Assuming they beat Nebraska, Purdue, Maryland, and northwestern at home...In order to go 7-8 they would also have to pick up 3 road wins or 3 more quality home wins....and that’s assuming you don’t count northwestern, Maryland, and Purdue as quality wins.
So you are either 10-10 in the best conference with
7 quality wins
Or 4 quality wins and 3 decent road wins
Or some combo
zero bad losses, and if they do pick up a loss at home to Nebraska and still get to 7-8...that would be countered by another quality win at home or another win on the road.
so in answer to your question...zero chance 17-10 (10-10) gets left out
