Iowa State vs. Baylor decides the #3 seed regardless of what happens with ISU vs. Missouri. The only way this isn't true is if ISU wins out and Missouri loses to Texas Tech, in which case ISU would get the #2 seed. If ISU wins out and Baylor and Missouri win their other games, ISU finishes tied with Missouri for 2nd with Missouri having the tiebreaker. So (barring a miracle) the Missouri game has no implications for Iowa State in the Big 12 standings. The good news is that the worst the Clones can do now is a #4 seed and that isn't so bad, in fact, I would argue that an ISU vs. Kansas is a better matchup in a potential semi-final game.
