I honestly don't know what I'd rather have.. 14-15 wins at the end basically knowing those two wins wouldn't have guaranteed a berth, or getting to 16-17 wins, not getting in and those two games being the reason why we missed the tournament.
Look at it this way --
There are likely to be at least a handful (if not more) games that come down to the last possession in the Big 12. Some of those will go our way and other teams will be like, "If only we won that Iowa State game," and some of them are going to come out like the FAMU debacle and the nut shot at the end of regulation against TCU.
Move those close wins/losses between the columns a little and, for any decent season, you can probably construct yourself a narrative of being "this close."
I do agree with you on FAMU and TCU, though. Those two are going to be hard to forget if it comes down to that. Our maximum win expectations --
FAMU = 97.8% (at the tip-off, unfortunately)
TCU = 93.9% (right before the banked in the three-pointer)
They even had around an 80% win expectation when up one late against FAMU. They needed one more stop against that and, well, we know what happened.
Those are two that were about as close to the win column as they get.
