From a purely statistical standpoint the odds are probably close to:
0-1 Wins - 2%
2 Wins - 8%
3 Wins - 25%
4 Wins - 40%
5: Wins - 25%
4-5 wins seems like a very reasonable expectation and 3 would be a bit disappointing IMO. Anything less than 3 is a disaster.
According to a probability calculator (KenPom odds that I simplified a tiny bit), yeah basically:
5 wins = 30.09%
4 wins - 41.71%
3 wins - 21.96%
2 wins - 5.48%
0-1 win - 0.68%
So we should win 4 or more ~72% of the time. I am afraid we'll drop 2 in this stretch, and it does seem that would be a decently large disappointment (less than 1/3 chance), unless we're a little bit overrated (which we probably are).
As mentioned, the Nova odds are actually relatively the same with Whitmore back. Creighton has also re-gained all the statistical ground they lost with Kalkbrenner out.
