By ESPN win probabilities, there is a 0.014% chance of this happening... So yeah, there's a case where it happens
Here's the odds of winning each game individually and the odds of being undefeated through that game (listed in parentheses)
- @Wyoming 86.4% (86.4%)
- Kansas St 33.9% (29.3%)
- @Baylor 44.2% (12.9%)
- Arizona 53.4% (6.91%)
- Oklahoma St 36.7% (2.54%)
- @UCF 18.3% (0.46%)
- @Utah 26.8% (0.12%)
- Kansas 42.6% (0.05%)
- @Arizona St 34.7% (0.02%)
- Houston 75.3% (0.01%)
Plus I'd emphasize that this (14 out of 100000 times) is probably an underestimate, given that the probabilities all move together and aren't actually independent. So odds are way better (140x) than the proverbial one in a million
