7-1 could do it. That's 23-8 (13-5) regular season.
Instead of comparing past years, let's take Lundardi's current bracket as a baseline.
6's are Notre Dame, Creighton, Oklahoma State and Minnesota.
If Iowa State lost only at OU, the resume would be in ballpark of those teams' current body of work (probably better than Creighton's) ... let's suppose all of them (or teams nearby) hold that slot. They'll most likely have a least a few other good wins and no drag-down losses.
I won't attempt a guess at Big 12 tournament, because I'm not sure where ISU would finish (that would effect how soon they could face an opponent that would move the needle at all).
