I definetly wouldn't expect them to. They've got a shot, but winning the remaining three matches would give us a 16-14 overall record and 11-9 in the Big 12. The best out of conference win would have to be considered BYU at home, and while BYU was ranked at the time, they've taken a sharp turn downward over the course of the season and are currently 5-9 in their conference matches. The best conference wins would be Iowa State and Baylor. Iowa State will likely finish in 4th in the conference and should be headed to the NCAA's, but Baylor will likely lose at least one (Nebraska) and probably two or three of their remaining matches (since they are without their top middle blocker, Anna Breyfogle) to fall into sixth place or worse in conference.
Our record wouldn't indicate a tournament bound team, but by winning our remaining three matches we should finish in at least 5th place in conference and the Big 12 seems to always get at least 5 teams in to the NCAA tourney, although the rest of the conference outside of the top three are kind of struggling this year.
We do know one thing for sure, and that is that the only way to have a chance at making the NCAA's is to win out, so that is priority number one. If we can manage that, then I guess our fate will once again rest in the hands of the tournament committee.
